Explain The Function Of The Lymphatic System

Consequently, the efferent arteriole, which filters blood away from the glomerulus, is tinier in diameter than the afferent arteriole, which carries blood into each glomerulus. This puts blood under high pressure in the glomerulus; thus it forces tiny molecules and liquid out of the capillary and into the Bowman’s capsule. Soon afterwards, the tiny and liquid molecules cross the epithelium of the Bowman’s capsule, the basement membrane and capillary wall in order to get into the Bowman’s capsule and to arrive in the nephron tubules. The consequence of this is that the filtrate (the tiny and liquid molecules) pass along the remainder of the nephron and helpful substances are reabsorbed along the route. Last of all, “the filtrate flows through the collecting duct and passes out of the kidney along the ureter” as mentioned by (Parson’s, R: p128).

2. Describe and give at least one example of each of the functions of the integumentary system.

Complete the table below for the required systems listed. You are required to list four to six of the main organs of each body system, one or two sentences explaining the function of the system itself in your own words, and a short list of five to six major diseases that afflict each system.

3. Describe the primary functions of each type of body tissue and give examples of each.

Explain what they are, their functions and where they are found. Then go into detail about two organs, with their functions, what tissues they are made of and where they are found in the body.

movement of water in tissues and maintain the fluidity of mucus and other secretions [3].

Lymphatic massage was introduced in the 1930s by Danish physiotherapists Dr. Emil Vodder and his wife (Benjamin, 2010). His wife Astrid Vodder practiced naturopath. Emil Vodder studied at the University of Copenhagen for biology, botany, and mineralogy, later began showing interest in the physical medicine along with the lymphatic system. Vodder knew many scientists who had studied the mysterious “clear water” centuries ago, scientist such as Gaspare Aselli (1581–1626) who discovered the lacteal vessels in the lymphatic system, Jean Pecquet (1622-1674) described the cisterna chyli and the thoracic duct leading to the venous arch (Wittlinger, 2004). Olaus Rudbeck discovered the lymph vessels of the colon and rectum and confirmed that these vessels lead to the cisterna chyli as Aselli had described already. Rudbeck was the first who discovered that the lymph from the tissue runs into lymph vessels and to the thoracic duct back to the blood circulation. In the 18th century it was discovered that the whole body contained lymph vessels and that the task of the lymph vessel system is to absorb tissue liquid. Vodder and his wife moved to Paris, France in 1933 to practice the modality on his patients (Wittlinger, 2004). The concept of lymph drainage by massage therapy is similar to opening a valve of a tube filled with water and allowing the water to flow into another tube to release pressure and alleviate build up in the lymph nodes. The carefully circling pumping movements

The lymphatic system are a complex network of specialised cells and organs that defend the body against infection. Lymphatic organs include the bone marrow, spleen, thymus gland, lymph nodes, tonsils, adenoids, appendix and clumps of tissue in the small bowel. A function of the lymphatic system is to nurture and mature the B and T-lymphocytes (white blood cells vital to immune function). Cancerous changes can take place

The organs that make up the lymphatic and immune system are the tonsils, spleen, thymus gland, lymph nodes, and lymphatic vessels. 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 agranulocytes, or cells (-cytes) without (a-) granules (granul/o) in the cytoplasm. B cells are created from stem cells, which are located in the bone marrow. B cells respond to antigens by becoming plasma cells. These plasma cells then create antibodies. Memory B cells produce a stronger response with the next exposure to the antigen. B cells fight off infection and bacteria while T cells defend against viruses and cancer cells. A hormone created by the thymus gland called thymosin changes lymphocytes into T cells. The thymus gland is active when you are a child and slowly shrinks, as you get older. T cells bind to the antigens on the cells and directly attack them. T cells secrete lymphokines that increase T cell production and directly kill cells with antigens. There are three types of T cells: cytotoxic T cells, helper T cells, and memory T cells.

4) List the 11 organ systems of the body, identify their components, and briefly explain the major functions of each

Did you know the circulatory system comprises the heart, veins, capillaries and arteries? The system moves pure oxygenated blood in a continuous and controlled way from the lungs and heart so that blood can reaches every cell. Blood travels through a type of network of vessels that include capillaries that permeate every tissue of the body. Once it’s depleted of oxygen, the blood returns to the lungs and heart and the cycle continues.

Starling’s law: The hydrostatic pressure of the blood is normally nearly balanced by the oncotic pressure of plasma proteins .The net result is that there is a continuous movement of fluid from the intravascular compartment into the tissues via the pre-capillary arteriole, where it is either transported away by lymphatics, or reabsorbed in the post-capillary venule]

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 called

All living things must obtain and use nutrients, get rid of waste, interact with their environment, and perform other processes in order to live. The complexity of an organisms will determine the way the organisms will carry out these processes. Unicellular organisms are organisms containing only one cell such as bacteria and some algae. These types of organisms performs all of the process necessary for life using only a single cell. Multicellular organisms, on the other hand, are organisms that consists of more than one cell. These type of organisms require organ systems to carry out the life process.

The lymphatic system produces and stores cells that helps the body battle infection and diseases. The lymphatic system contains the following components: bone marrow, thymus, spleen, and lymph nodes. The lymph system allows the body to move fluids and cells outside the blood and circulatory system. The lymph system is the most important passageway
