The lymphatic system plays several essential roles in maintaining overall health and homeostasis in the body. The main functions include:
1) Fluid balance
The lymphatic system helps maintain fluid balance by collecting excess interstitial fluid from tissues and returning it to the bloodstream.
This prevents fluid accumulation in tissues, avoiding swelling and related complications.
2) Immune function of lymphatic system
As an integral part of the immune system, the lymphatic system transports immune cells like lymphocytes and facilitates their interaction with antigens in lymph nodes and other lymphoid tissues.
This supports an effective immune response against pathogens and foreign substances.
3) Waste removal
The lymphatic system removes waste products, cellular debris, and foreign particles from tissues.
These materials are filtered and eliminated in the lymph nodes, where immune cells break them down and remove them from the body.
4) Fat absorption
The lymphatic system aids in absorbing dietary fats and fat-soluble vitamins.
Lymphatic vessels in the intestines, known as lacteals, absorb these nutrients and transport them to the bloodstream for distribution to body tissues.
5) Transport of immune cells
Lymphatic vessels transport immune cells, such as lymphocytes, throughout the body, enabling them to reach infection or injury sites and perform their functions effectively.
