Function Of The Lymphatic System

Function Of The Lymphatic System The key function of the lymphatic system is to bring together and transport tissue fluids from the intercellular spaces that does gas exchange, water transport and also for ion movement into all the tissues of our body and then back to the veins into the blood system. It does an important role by returning plasma proteins to the bloodstream, and then digests the fats that are absorbed and then it transported from the villi into the small intestine then to the bloodstream thru the lacteals and lymph vessels. The new ones of lymphocytes are being factory-made in the lymph nodes antibodies and anti-assist that the body builds up an effective immunity to infectious diseases. The lymph node does an important role to protect mechanism of the body and it filters out micro-organisms such as, bacteria and foreign substances e.g. toxins. As it transports giant molecular compounds e.g. hormones and enzymes from their manufactured sites into to the bloodstream. The lymph nodes are small and they are bean-shaped like kidney It work as filter of the lymphatic fluid and as the lymph passes through the lymph nodes, pathogens present in the lymph activates lymphocytes and macrophages to destroy the microbes. Lymphatic vessels take place through the body beside arteries in the veins or viscera also in the subcutaneous tissue. They absent from the central nervous system to bone marrow, teeth, and avascular tissues. A lymph vessel transports the fluid it is called lymph, the lymph contains white blood cell that transports in and out of the bloodstream as its needed. If the body is attacked by a foreign substance, its often transported from the bloodstream into the lymphatic system for removal. The lymph vessels has not have central pump however, lymph needs to be transported by the peristaltic contractions of the vessels themselves. Lymphatic ducts are a main lymph vessel that gathers lymph draining from the right upper our body and head. The lymphatic duct is quarter-inch in diameter and about two inches long; it discharges into the right subclavian vein, delivering lymph into to the bloodstream. The thymus is an organ in the body controls the immune processes, the thymus procedure is a type of white blood cell that is known as a T-lymphocyte by this it means that they help our cells to recognise and destroy invading viruses, bacteria, abnormal cell growth e.g. cancer, and foreign tissues. Thymus gland helps to protect the heart along with the pericardium, as it produces hormones that stimulate the manufacture of certain infection fighting cells. In the children it helps immunity by producing white blood cell including T-cells. It atrophies as the child gets older therefore, person grows its roles becomes less so that the adults doesnt tend to have one as the bones and spleen take over those jobs. The spleens function is connected to the immune system or with the blood supply. The spleen get rid of the old red blood cells that is call erythrocytes from the blood supply and also removes stores and then produces white blood cell called lymphocytes. The lymphocyte produces antibodies and assists in removing microorganisms and bacteria from the blood supply. Task 2(M5) The lymphatic system maintenance the immune system in removing and destroying waste remains, toxins, dead blood cells, pathogens, and cancer cells. The lymphatic system absorbs fats and vitamins from the digestive system then delivers the nutrients to the cells where it uses it cells, also the lymphatic system get rid of excess fluid and also waste products from the interstitial spaces among the cells. The main maintain is the fluid and balance protein in the body, the lymphatic system performances as a minor circulatory system and plays a key role in continuing homeostasis good healthily. The Lymph is the fluid that is carried by the lymphatic system. It initiates as blood plasma the liquid component of the blood, after when it has been lost from the circulatory system due to hydrostatic pressure. Then the plasma leaks out of the blood vessel and into the surrounding tissues. Then it enters the lymphatic system once when its within the lymphatic system, the lymph has alike work to the original interstitial fluid, and the extracellular fluid that surrounds cells. The large gap between the cells is designed, which allows fluid, interstitial proteins and other e.g. bacteria to flow into the lymph capillary. The lymph has one way system that travels between the cells of the body, from the interstitial spaces to the subclavian veins just next of the neck. As the lymphatic system doesnt have no central pump like heart to pump it, its movement depends with the muscles and joint pumps. As it moves upper body towards the neck the lymph passes slowly through the lymph node that filters, it to remove debris and pathogens the neck lymph flows into the subclavian veins on whichever side of the neck. The fluid vertebral into the venous circulation of the circulatory system from the tissues in order to stop dehydration fights against the infections and recycle plasma protein. The blood carries nutrients, oxygen, and hormones for the cells. The 10% remaining of the fluid that stays in the tissues as its known as lymph. The 90% of this fluid then returns to the venous circulation through the venues and continues as venous blood. The (MALT) mucosa associated lymphoid tissue is immune responses to specific antigens come across alongside all mucosal surfaces, MALT inductive immune tissues where antigen sample occurs. The larger group function is like lymph nodes smaller, spreads MALT are mostly T lymphocytes also it has B cells and plasma cells. The IgA in the intestines and respiratory tract is to protect against pathogens that may access to underlay tissues. lymphatic-system Task 3 (D3) Infection of the Lymphatic System Lymphedema: One of the disorders which occurs due builds-up of lymphatic fluid in the interstitial tissue. The affects is swelling in the arm, legs and in other part of the body. The harshness of this disorder varies an abnormal virus which is painful, disfiguring and cellulite infections deep in skin. If this doesnt get treated, the skin eventually becomes fibrotic thickening of the skin and subcutaneous tissues losing normal structure, functionality and movement. There are two types: Primary Lymphedema: Is genetic condition that occurs due to impaired or missing lymphatic vessels, which can affect from one to several as four limbs at other part of the body this may carry an internal organ which could be exhibited at birth, develops onset of puberty or happens in adulthood without any apparent causes. Secondary Lymphedema: is basically developed regional lymphatic insufficiency which occurs due to infection, any operation or suffocating that disrupts the lymphatic vessels or even loss lymph nodes. http://i3.squidoocdn.com/resize/squidoo_images/-1/lens8897831_1262976791exercise_for_lymphedema.ghttps://www.vascularweb.org/vascularhealth/PublishingImages/NorthPoint%20Images/Lymphedema_01_Base_225.jpg There are a few abnormal count of the patients blood: His Red Blood (Platelet count) is in the normal range, but its very low His white blood cell count is higher than the normal average range, its 15.0 when its meant to be between 4.0 -6.0 His Basophilis and Eosinophils both are very low His Lymphocytes is too high, its over the normal range His Monocytes is in the average but its high The underlying mechanisms that could have produced this abnormal blood count in a patient with Lymphoma, is because Lymphoma is a cancer that attacks the white blood cell by that the patients blood count to have Lymphoma. Patients with lymphoma produce abnormal lymphocytes, which they are white blood cell. Lymphocytes are mostly found in the lymphoid tissues and lymph nodes, which that make the lymphatic system. this is where lymphoma occurs

Cellular Respiration Lab Report Essay -- essays research papers

Cellular Respiration Lab Report I.Introduction In this lab we are measuring the amount of oxygen used in both germinating and non germinating peas. We are measuring the oxygen consumption by taking a reading of a respirometer submerged in two water baths. The first bath will be cold water and the second warm to determine the effect of temperatures on oxygen consumption. Our negative control will be glass beads to measure to increase or decrease in atmospheric pressure or temperature changes. There is a direct relationship between oxygen consumption and Carbon Dioxide produced, therefore the more O2 consumed the more CO2 produced. To keep the amount of CO2 produced from canceling out any pressure gained or lost from the consumption of CO2 we are adding KOH(Potassium Hydroxide) to the respirometers. Since the CO2 will be selectively removed the change in the volume of gas in the respirometer should be directly related to the oxygen consumed. In this experiment the germinating peas, in both water baths, should consume much more oxyg en than the non-germinating peas or the glass beads, because germination has began thus accelerating cellular reactions and the rate of respiration. The cold water bath should slow the respiration down in all three respirometers. II.  Ã‚  Ã‚  Ã‚  Ã‚  Materials and Procedures. For this experiment we have prepared to water baths. One bath is ice water, around 10 degrees Celsius, the other warm, around 25 degrees Celsius. Both water bath...

The Book Of Sand Essay examples -- essays research papers

Jorge Luis Borges is a famous Spanish author, known best for his short stories. In this paper, I will discuss several short stories written by Mr. Borges, what influenced him in his writings, and a brief history of his place of origin, Argentina. Borges' The Book of Sand is the story of a man who is visited by a stranger trying to sell a "holy book" called the Book of Sand. The narrator looks at the book and is unable to see the first or last pages of it because, as the stranger explains, the number of pages is infinite. The narrator is fascinated by the book and buys it, only to become obsessed with it, until the point that it is all he thinks about. He eventually gets rid of it by mixing it up in a pile of many other books in his basement. As will be discussed in this paper, Borges wrote philosophy in a lot of his works. In The Book of Sand, infinity is depicted in the form of a mysterious book. It symbolizes man's constant search for the world's existence. Borges is saying that it is an endless search and therefore pointless. The Other is the story of Borges sitting on a bench, as he feels as though he had lived that moment already. He begins to speak to the man seated besides him, and finds out the stranger has the same name, and the same address as he does. When Borges asks the man what year it is, the man answers 1918, even though it is 1969. It is then that the narrator figures out he is talking to the person whom he was fifty-one years earlier. He then tells "the other" him of the future, after which they part, knowing they will never meet like this again. This story deals with time. The author is very nostalgic and lives for his memories. It also is a philosophical story where Borges expresses his doubt that we all may "just be an image of a greater being". The Mirror and the Mask is the story of an Irish king who tells a poet to write a poem describing his power. The poet wrote a praise of his fighting success, and in reward for the excellent poem, the king gives the poet a beautiful mirror and tells him to write another poem. In reward for his next work, the king gives the poet a mask. The king then asks for a third poem and receives a one line poem of perfection and in return gives him an elaborate dagger. The poet feels it to be a sin to hear such perfection and so he stabs himself with the dagger. The king ... ...s for his interest in eternity and his desire for control of time. He admits in his poems that time moves on, the world changes, that he will grow old, and that the past is gone forever. He says that one can only rely on their memories (as he expresses in The Other). In his fifties, Borges becomes blind, but continues to lecture in colleges and conferences around the world. During his lifetime, Borges was nominated several times for the Noble Prize in Literature. He wrote alot of short stories, literary reviews (based on books that never existed), poems and more. Although he passed away on June 14, 1986, his writings live on to be shared with all generations. When Borges was born, Hipolito Yrigoyen headed the Radical Civic Union. General Roca was president at that time and he defended the middle class (which was what Borges was). Argentina had alot of trade with Britain and helped the economy to flourish. The people became more educated. As you can see, Borges' greatest influences were his childhood, familial background, and people he met while starting to write. Borges writings are enjoyable and thought provoking. I definitely recommend it to people interested in philosophy.

Economic Networkingâ€Exploring Alternatives for Promoting Sustainable De

Economic Networking—Exploring Alternatives for Promoting Sustainable Development in Africa INTRODUCTION The history of European aid intervention in the African, Caribbean and Pacific (ACP) states has traditionally acted to reinforce the hierarchical distinction between the â€Å"developed† and the â€Å"developing† world. The series of Lome Conventions which granted preferential trade agreements between these groups of countries have proved ineffective in encouraging economic sustainability in the ACP states, and although the ACP includes most of the Least Developed Countries (LLDCs) in the world, the agreements have been criticized as being unfair in the global context. Under pressure to negotiate a new ACP-EU agreement that would be consistent with World Trade Organization (WTO) regulations, and improve on the limitations of the previous Lome Conventions, the Cotonou Convention was signed in 2000, after arduous negotiations. Despite this agreement, the future of ACP-EU relations is somewhat vague. Particularly with respect to Africa, this uncertainty leaves room for eva luation of the effectiveness of the past agreements and an objective analysis of the motives behind previous economic ties. Furthermore, by analyzing the problematic history of European aid to Africa, there emerges a basis for shifting away from the neo-colonialist relationships that characterized most of the past agreements, and exploring the benefits of creating alternative partnerships. Ultimately, the possibility of forming partnerships amongst individual ACP countries and between other developing countries is an overlooked idea that should be further explored.

Learning Activaties Essay

When working with children especially children who you support in class you will be given the opportunity to input your own ideas into the teachers planning, as you have your own areas of expertise or if you are a one-to-one you will have your own knowledge of the child you work with. When you work with children with special needs they will need more structure in the activities that they do every day and you will be aware of their strengths and weaknesses. The child that I work with in school has a range of difficulties from social communication difficulties to a speech and language problem. Everyday is different because he is so interchangeable, one day he will sit and work with me and the next he will not want anything to do with me, sometimes this makes it hard as most of the work we do is structured around work given by various professionals who come into school to support him (speech and language, education psychologist, communication and interaction team and learning support). Because I work with him every day I can see what works with him and what doesn’t and just about daily I have to give feedback to her so that we can both plan the lessons for him for the next day. Here are a few examples of when I have offered constructive suggestions in supporting planned learning activities:- I was sat with the teacher one morning before the children came into school because that is when we do our planning for the child I support or we modify anything that he has to be supported with in class. I noticed that the teacher had planned an arts and craft lesson that involved the use of tissue paper, the child that I support does not like the touch or feel of tissue paper (I had done an activity with him the other week which had resulted in him refusing to anything else with the tissue paper has he did not like the feel he got so upset and I had to put the tissue paper away). I mentioned this to the teacher because I wanted my child to be involved with the lesson but I did not what them to disrupt the rest of the class. So we decided that we would alter the materials we were using not just for the child that I support but for the whole class so that he could feel included in the whole lesson. Another example was when I was working with a group of children doing a numeracy lesson. The lesson was about rounding numbers up to the nearest ten, I had a group of six children one of which as special needs first the teacher explained to them in class what they were expected to and told them how to do it, I then took the six children out side of the class and supported them with the lesson. The children found the task very difficult and could not grasp the idea of rounding off numbers to the nearest ten. When I took them back into the class room I talked to the teacher and explained that most of them found the task hard and suggested that we modify the task by letting them use a number line to help then see how to round the numbers off to the nearest ten. She agreed that i was right and said that it was a good idea for tomorrow’s numeracy lesson. By doing this I gave constructive suggestions to the teacher and supported planned learning activities.

American Modernization Essay

Modernization. This has been a feared word in the past and even today. For example, in the Great Gatsby, by F. Scott Fitzgerald, Gatsby is trapped living in the past and is disillusioned by modernization. Additionally, in the story A Rose for Emily, Emily is also afraid of modernization because she is trying to escape death by holding onto her father’s dead body. She is afraid to move on in her life and decides to hide in her past. Lastly, in one of Langston Hughes poems called Mother to Son, he writes about how in the early 20th century African Americans were not equal to white people and then society began to modernize blacks to become equal. This led to segregation because the white people wanted to isolate themselves from African Americans. Because their dream of what society should be was disillusioned, just like in all three of these literatures. Therefore the results of modernization, isolation and disillusionment was that many people didn’t except a change their life. Gatsby wanted to feel like he was living in the past with Daisy but he was isolated and disillusioned because he was living in a modern society. Additionally, he was isolated because he could not have a social status or Daisy. In the book, Gatsby was a fantastic character because he wanted to hide in the past with Daisy when everything was perfect. While the other characters in this book went with the change of society. Also in the book, Gatsby’s yellow car symbolizes the modernization. Gatsby’s car accidently kills Myrtle, which eventually leads to his death. Gatsby cannot escape modernization or his own death at the end of this book. Lastly, Gatsby surprisingly takes the blame for Myrtles death because this is what he thinks will help him keep living in the past with Daisy. This makes it very clear that Gatsby is isolated and a disilluded character. Just like Gatsby, Emily is also afraid of modernization. An example of this would be the house that Emily lives in is from the early 1800s, and she hides in this house to cover up all of the changes in society that surrounds her. Emily is a very strange woman and is very afraid of modernization. This is why when her father passes away she keeps his body so she doesn’t feel isolated. Emily is also disillusioned because she tries to live in the past to escape death which cannot happen. In addition, death triumphs over her life due to the fact that she kept her father’s dead body. Emily then tells the police that her father is not dead, and that he is inside the house now. She does this to make her feel like she is living in the past with her father. This feeling of having him at home, even though he is gone, makes her feel like she is living her dream. The modernization makes Emily go crazy in her attempt to hold onto things and how they were in the past. In the time of segregation, Langston Hughes was isolated because he was a different race then the superior race which was white. He was laughed at and looked down upon when he said he wanted to write for a living. As time goes on and segregation becomes less followed the white people are disillusioned because their ultimate dream of society was ruined. Additionally, the whites isolate themselves from African Americans because they are disillusioned and disappointed by modernization. For example, when Langston Hughes says in Mother to Son â€Å"Life ain’t been no crystal stair. It’s had tacks in it, splinters, and torn up boards†. This shows how whites treated African American so poorly. As this poem goes on, he states â€Å"But all the time I’ve been climbin on and reachin landins and turnin corners†. This means that things are gradually getting better for Langston and other African Americans. This means the white people isolate and disillusioned themselves from their dream of society. The white people are extremely afraid of modernization, plus they want the society to be how it was in the past as them being superior over the African Americans. This happens to Gatsby, whites, and Emily. They all want things to either be how they were in the past, or how they all know but either way they are all terrified of modernization. Therefore, Modernization resulted in isolation and disillusionment in the early American 20th century because the unbearable truth of reality makes you lose faith in all that you do. In all three of these stories, people try to hold onto their past even though it will lead to extravagant consequences. Gatsby, Emily, and The Whites do these things to convince themselves they are living their dream in the past where everything is perfect, but in reality they are isolating themselves and losing their faith in life. Modernization causes people to ultimately lose faith in all that they do. Also Modernization cannot be escaped for anyone, which then separates these people from normal people who can accept society and its changes. Modernization is a feared word in today’s society and will be forever.

My Bloody Life Claims

In Chicago, one gains power that is attained only by being ruthless. This can be shown in the book My bloody Life, by Reymundo Sanchez, that takes place in Chicago. Throughout this book, Reymundo points out the ruthlessness in the main character that gains his power only by being that. Reymundo quotes, â€Å"I was digging up my own grave because I wanted to be accepted. I wanted to be looked up to. The only way I knew of achieving this status among the gang members was to commit as many violent acts as possible†¦ Finally those around me stopped thinking of me as a coward, R.S 114. † Reymundo shows that he acknowledges the fact that he is digging up his own grave by committing crimes. His ruthless character is shown by when he says, â€Å"achieving this status†¦was to commit as many violent acts as possible. † To reymundo, in order to gain his power he had to be looked up to, and the only way that he would be looked up to is by committing as many violent crimes as possible. In Chicago, power is abused to suppress the lower class.This can be shown in the book My bloody Life, by Reymundo Sanchez, which takes place in the city of Chicago. In the book there are several scenes where innocent lower class people are not treated fair, because of their status. Reymundo says, â€Å"Gang members as well as non-gang members feel they need to run and hide when the police are present. If they didn’t, they would be harassed beaten or arrested for a crime they didn’t commit.Police tend to believe that kids in the ghetto are guilty unless proven innocent. That’s why kids run, and the police are the enemy, R. S 231. † This quote shows the mentality of the lower class whether they are gang or non-gang members. The fact that instead of having a fair trial, the lower class are harassed, beaten or arrested for a crime they did not commit shows the suppression on the lower class that is being abused by the ones with power.
