![]() One of the major lymphatic vessels is the thoracic duct, which begins near the lower part of the spine and collects lymph from the pelvis, abdomen, and lower chest. The heart, lungs, intestines, liver, and skin also contain lymphatic tissue. The major parts of the lymph tissue are located in the bone marrow, spleen, thymus gland, lymph nodes, and the tonsils. The lymphatic system is a network of very small tubes (or vessels) that drain lymph fluid from all over the body. The lymphatic system also impacts diseases such as excessive obesity caused by abnormal fat and carbohydrate metabolism. A malfunction of this part of the lymphatic system can result in serious malnutrition. Lymph vessels in the lining of the gastrointestinal tract absorb fats from food. ![]() The spleen contains lymphocytes and another kind of white blood cell called macrophages, which engulf and destroy bacteria, dead tissue, and foreign matter and remove them from the blood passing through the spleen. The spleen also helps the body fight infection. The body’s first contact with these invaders signals the lymphatics, calling upon this system to orchestrate the way the infection-fighting cells prevent illness and diseases from invading microorganisms. This network of vessels and nodes transports and filters lymph fluid containing antibodies and lymphocytes (good) and bacteria (bad). It is the first line of defense against disease. The lymphatic system plays an integral role in the immune functions of the body. The lymphatic system collects this fluid and returns it to the circulatory system. This loss of this fluid (approximately 1-2 liters/day) would rapidly become life threatening if the lymphatic system did not properly function. Production of immune cells (such as lymphocytes, monocytes, and antibody producing cells called plasma cells).Īs blood moves through the arteries and veins, 10% of the fluid filtered by the capillaries, along with vital proteins, becomes trapped in the tissues of the body.Absorption of fatty acids and subsequent transport of fat, chyle, to the circulatory system.If the lymphatic system didn’t drain the excess fluid from the tissues, the lymph fluid would build up in the body’s tissues, and they would swell. This process is crucial because water, proteins, and other substances are continuously leaking out of tiny blood capillaries into the surrounding body tissues. The removal of excess fluids from body tissues.The lymphatic system has three functions: The spleen, which is located in the upper left part of the abdomen under the ribcage, works as part of the lymphatic system to protect the body, clearing worn out red blood cells and other foreign bodies from the bloodstream to help fight off infection.
