What are the lymphatic system organs?

The organs of the lymphatic system are your: Bone marrow. This is the soft, spongy tissue in the center of certain bones, like your hip bone, backbones and breastbone. Your bone marrow has the vital job of making white blood cells, red blood cells and platelets. Thymus. This organ is located in your upper chest beneath your breastbone, and it’s most active before puberty. It’s where T-cells (a type of white blood cell) fully mature. T-cells help your body fight off invaders. Lymph nodes. Lymph nodes are bean-shaped glands that monitor and cleanse lymph as it filters through them. They clear out damaged cells and cancer cells. Your lymph nodes also store lymphocytes and other immune system cells that attack and destroy harmful substances like bacteria. You have about 600 lymph nodes scattered throughout your body. Some are closely connected in groups called chains. You may be able to feel some lymph nodes through your skin, in areas like your armpits, groin or neck. Others are deeper inside your body. Spleen.

Common infections that can cause enlarged lymph nodes include strep throat, mononucleosis, HIV and infected skin wounds. Lymphadenitis refers to lymphadenopathy that’s caused by an infection or inflammatory condition. Swelling or accumulation of fluid (lymphedema). A blockage in your lymphatic system due to scar tissue from damaged lymph vessels or nodes can cause lymphedema. It can also happen when your lymph nodes have been removed to treat a condition like cancer. With lymphedema, fluid most commonly builds up in your arms or legs. It can be very mild or quite painful and disabling. People with lymphedema are at risk for serious and potentially life-threatening deep skin infections. Cancers of the lymphatic system. Lymphoma is cancer of the lymph nodes that occurs when lymphocytes grow and multiply uncontrollably. There are several different types of lymphoma, including Hodgkin’s lymphoma and non-Hodgkin’s lymphoma. Cancerous tumors can a…
