What is the lymphatic system?
The lymphatic system is a network of vessels through which lymph drains from the tissues into the blood. The lymphatic system helps protect our bodies from infections and diseases. It is part of the immune system as well as the circulatory system and is made up of a number of lymph vessels, lymph nodes and lymphatic tissue and it is a vascular network of tubules and ducts that collect filter and return lymph to blood circulation. Lymph is a clear liquid that comes from blood plasma that is based at the capillary beds it exits through the blood vessels. This fluid surrounds the cells. The lymph consists of water, proteins, salts, lipids, white blood cells and other substances which have to be returned to the blood.
The lymph vessels accumulate lymph fluid from the tissues of the body and then return it to the blood, this than helps maintain the body’s balance of fluid. The lymph nodes filter the lymph; these contain specific white blood cells called lymphocytes. Lymphocytes are formed within the bone marrow, spleen and thymus, also they help the body protect itself against infection.
Function of the lymphatic system:
The functions of the lymphatic system is to drain excess fluid that surrounds the tissues and organs and which then returns the fluid to the blood; this helps the volume of blood and the blood pressure to be maintained, it also prevents fluid around tissues building up excessively. The lymphatic system absorbs and returns lipids
ANSWER: The cell composition of blood composed of erythrocytes, leukocytes, and platelets where all except the WBCs perform their functions within the blood only which involves transport and coagulation for platelets. While the interstitial fluid like water within the spaces between cells. Lymph is just like leaked blood that is collected by the lymphatic system but cleansed of any foreign or waste materials because of lymph nodes (6, 5, 1 p. 400 ).
Red and white blood cells are the two types of blood cells in the human body. Red blood cells transport oxygen around the body which is transferred through the bloodstream. It moves oxygen into the body and then removes it. They are absorbed through its haemoglobin.
The functions of the renal system, which are performed by the kidneys, are to regulate and maintain the balance of electrolytes and the pH of the fluid that has been processed. It assists in the production of new red blood cells and it also involved in the maintenance of blood pressure.
Works in conjunction with the blood supply to carry waste products away from the area.
It collects excess fluid and particulate matter. It deposits them in the blood stream through the
One of the most important organs of the lymphatic system within the body's blood filter process is the spleen. This organ does a variety of things to help keep healthy blood available to be shipped to the body for pathogen-fighting purposes. The spleen normally is about a fist size. The oval clump of blood vessels intertwined with strands of connective tissue is separated into two parts. The blood vessels that make up a large content of the spleen, are called splenic sinusoids. The organ is normally found in the left upper part of the abdomen, above the stomach, it is mostly protected by the lower ribs. This particular organ is a definite vital part in cleaning the body's blood supply. In most cases people can live without their spleen (Rettner, 2013). This of course comes with extra precautions to help fight infections but a normal life can exist. The dark purplish red mass helps to filter the blood through its many passageways of blood vessels and is soft in texture.

William Li mentions the blood vessels in his talk. Human’s body is literally packed with them. The smallest blood vessels are called capillaries, it is the vessels of life and are feeding cancer cells, bringing oxygen and nutrients. Also, it can be the vessels of death. We have got nineteen million of them in our bodies. Blood vessels are adapt our bodies no matter where they grow in our bodies.
spleen is a place for immune function, and it kills defective or aged red blood
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 purpose of this exercise is to learn about the lymphatic system and how it works and helps the human body. Why we need it and the components associated with the lymphatic system.
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.
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,
The circulatory and immune systems are two very closely related systems. The circulatory is composed out of blood vessels, the heart, and blood. The immune system is made up of white blood cells and various lymph nodes. Basically, most of the immune system is found inside the blood of the circulatory system. The circulatory system provides the body with blood. It gives the kidneys of the digestive system something to filter and picks up nutrients from the small intestines. It also picks up air from the lungs of the respiratory system and provides the brain of the nervous system with blood, along with the rests of the body. Protection from wounds in the integumentary system is also provided by the circulatory system which has platelets that aid in blood clotting and forming scabs. The immune system protects all the other systems from disease and helps them from being attacked by viruses and bacteria. It also aids the ears of the nervous system with some very protective earwax. The circulatory system provides us with life fluid while the immune system protects that fluid and the rest of our body.
