The lymphatic system acquires a complex chain of vessels, tissues, and organs. So, how do vessels, tissues, and organs work together in unison to get rid of waste in the body and help defend the body against infection? There are hundred of lymph nodes in the human body, they are located around the heart and lungs. Some are closer to the surface such as the groin and arm. The spleen, which is located above the kidney, is considered to be the largest lymphatic organ. It detects any bacteria in the blood. Once bacteria is detected, lymphocytes are created and attack the bacteria. Overall, the lymphatic system maintains the body healthy by getting rid of any viruses.
A lymph acquires nutrients, oxygen, hormones, and fatty acids. It is a fluid that comes from blood plasma and is pushed out through a wall known as the capillary. Lymphs also carry lymphocytes (small white blood cells) which enter the bloodstream. Lymphatic vessels are tubes that are located deep in the body.
As shown in the article Lymphatic System Anatomy it says, “The lymphatic vessels grow progressively larger and form 2 lymphatic ducts: the right lymphatic duct, which drains the upper right quadrant, and the thoracic duct, which drains the remaining lymphatic tributaries” (Praveen Buddiga, 2013). Lymphatic vessels resemble veins, they have a one way valve that prevents any backflow. The lymphatic vessels then make its one-way journey to the subclavian vein which is at the base of the neck. The lymphatic system’s role in immunity is to produce white blood cells (lymphocytes) which aid in getting rid of any disease/infection harming the human body. The organs and tissues of the lymphatic system are the main sites of production of two types of lymphocytes: T lymphocytes and B lymphocytes. They are also known as T cells and B cells. Both T cells and B cells are likely to encounter foreign microorganisms. The spleen also aids in protecting the body from infection.
It contains lymphocytes and macrophages. These two destroy bacteria, dead tissue, and removes foreign matter. Lipids in the lymphatic system are transported from the enterocyte into the blood. The transportation of lipids into the circulation is different from sugars and amino acids. In the article Absorption of Lipids it says, “Instead of being absorbed into the capillary blood, chylomicron are sent first into the lymphatic vessels” (Bowen).
It later drains into the lymphatic system. Protein molecules leak through the capillary wall. This will increases the pressure of the interstitial fluid. Due to this, blood volume and blood pressure decrease and the volume of tissue fluid increases. This results in swelling.
