The Lymphatic System Essay - 881 Words

The lymphatic system is very similar, and works with and directly at the side of the cardiovascular system. The lymphatic system has a network of vessels like the circulatory system which pump a plasma-like fluid called lymph around it’s own lymph vessels, and are found in most other tissues of the body, except the central nervous system. Lymph is the name given to the fluid of plasma proteins that escape the circulatory system at the sites of the capillary network and diffuse into the cells around the capillaries. To enable the body to maintain a homeostatic fluid level and pressure, the lymph must be returned to the circulatory system. The way this happens is for the the network of lymph vessels to pick up the fluid which has escaped,†¦show more content†¦The act of breathing alters the pressure within the thoracic cavity and as the pressure drops, this also helps to force the lymph through the network of lymph vessels which have smooth muscle to aid the circulation. The structure of the lymph vessels are very similar to those of the circulatory system vessels. A protective outer layer, a muscular central core and a smooth inner lining to aid the free flow of lymph. Failure to circulate lymph back to the circulatory system results in swelling of the tissues, or oedema. Examples of this can be the result of infection through tropical disease where the lymph vessels are destroyed or blocked, or mild, temporary cases such as pregnancy where the weight of a foetus can press against the lymph vessels and prevent the return of lymph to the subclavian ducts. The lymphatic system works in three ways. It helps to control the balance of the body’s fluids by draining and cleansing fluid that seeps from the circulatory system during normal cardiovascular circulation. As fluid leaves the circulatory system it enters the tissue cells and whilst the majority of it diffuses back into the vessels of the circulatory system, the remainder enters the open ends of the lymph vessels. The lymphatic system also works with the villi in the digestive system to help deliver fats and absorbed nutrients in the digested food we eat, back to the circulatory system. This fluid is not calledShow MoreRelatedThe Lymphatic System862 Words   |  4 Pagesof our lymphatic system is vital to the health of our whole body.

How are lymph capillaries structurally and functionally SIMILAR to blood capillaries? ANSWER: The structures between the two are similar in a way that they look like a web or roots, and they both function to collect and return blood to the heart from the blood cycle (1 p. 399). B.

White blood cells (leukocytes), red blood cells (erythrocytes), plasma, and platelets (thrombocytes) make up the blood. Lymphocytes are leukocytes (white blood cells) that help the body fight off diseases. Two types of lymphocytes are B cells and T cells. Lymphocytes recognize antigens, or foreign substances/matter, in the body. Lymphocytes are a classification of agranulocytesRead MoreLymphatic And Immune System :831 Words   |  4 PagesLYMPHATIC IMMUNE SYSTEM: The body encounters billions of germs every day and the immune system with all its intricacies fights off these pathogens.
