The Lymphatic System
The lymphatic system plays a huge part in our bodies. It is essential for us to maintain a good health. It is a very complex system that is connected to the immune system. The lymphatic system acts as a one way drainage system The primary function of the lymphatic system is to transport ‘lymph’ which is a clear fluid that contains white blood cells (lymphocytes) and drain it back into the blood. This helps get rid of; toxins, waste and any foreign bodies within a human. The lymphocytes are cells of the immune system which helps the body to fight diseases. There are two types of lymphocytes; T and B lymphocytes. Unlike our blood, which travels through the body in a continuous loop, lymph only travels in one direction which is up towards the neck, within its own system. The tissue fluid flows into our venous blood stream through specific veins which are located near our collar bones. Then, after delivering nutrients the plasma leaves the cells with debris. Most of the tissue fluid will then return to the venous circulation and continues as venous blood. Lymph leaves the tissue and enters the lymphatic system through lymphatic capillaries. ¾ of these capillaries are superficial and are located near the skins surface. There are even deep lymphatic capillaries that surround most of our body’s organs. The lymphatic system also has two drainage areas, the right drainage area handles the right chest and arm and the left drainage area clears all other areas of the body, including our legs! The lymphatic system is made up of tissues and organs that consist of lymph vessels, lymph nodes and lymph’s. Also in the lymphatic system are the tonsils, spleen, adenoids and thymus. The spleen is that largest lymphatic organ and is located just above the kidney. We are able to live without a spleen but are more prone to infection. It is involved in the;...
