Lymph's full form is lymphatic fluid. It's a clear, watery fluid originating from plasma (the liquid part of blood) that seeps through blood capillary walls into the spaces surrounding cells. This vital fluid plays a significant role in the body's immune system.
Composition and Function
Lymph is primarily composed of:
- White blood cells, especially lymphocytes, crucial for attacking bacteria.
- Minerals
The lymphatic system, a network of organs, vessels, and tissues, moves this lymph throughout the body. Its primary functions include:
- Immune response: Lymphocytes in lymph target and destroy pathogens.
- Fluid balance: Lymph collects excess fluid from tissues, preventing swelling.
- Fat absorption: Lymph absorbs fats and fat-soluble vitamins from the digestive system.
The lymphatic system is integral to the body's defense against infection and maintaining fluid balance. Conditions affecting the lymphatic system, such as lymphatic filariasis (elephantiasis), or cancers originating in the lymphatic system (lymphomas), highlight its importance. Analysis of lymph nodes (collections of lymphatic tissue) is often used in cancer diagnosis and staging.
