what does the lymphatic system do?

Question

what is the purpose of the lymphatic system and lymph? and does swelling relate to the lymphatic system in any way? if it does, plus specify how. thanks.

Answer 1

The lymphatic system removes excess fluids from body tissues, absorbs fatty acids, transports fat to the circulatory system, produces and transports white blood cells in immune responses. Lymph is actually the blood plasma that leaks from capillaries and has diffused into lymphatic organs for processing before returning to the circulatory system, which serves as the vehicle of white blood cells. Damage or interference in the function of lymphatic organs can result in bodily swelling. Since the organs are not functioning correctly, they are not absorbing the interstitial fluid that would become lymph when absorbed. Thus, the fluid just continues to collect in the body, causing it to swell. A similar phenomena occurs when there is a blockage in lymphatic veins. Problems such as these occur for a number of reasons, but the most common ones today are usually associated with certain types of cancer.

Answer 2

The cells of the body are suspended in "extracellular fluid" or "interstitial fluid". This is the pathway of gases and nutrients between capillaries and the body's cells. There is a delicate balance of fluids between cells and their environment, and it is the job of the lymphatic system to maintain fluid levels in this extracellular environment. So, the main function of the lymphatic system is to drian excess fluid. Additional functions include transport of fatty acids, and synthesis and transport of immune system cells.
