Lymph is a colorless fluid that circulates through the lymphatic system, a network of vessels, nodes, and organs. Derived from interstitial fluid surrounding cells, lymph contains white blood cells, proteins, and waste products.
Lymph plays a vital role in immune function by transporting immune cells, filtering out foreign substances, and helping the body combat infections. It also contributes to fluid balance, returning excess interstitial fluid to the bloodstream.
This essential component of the immune and circulatory systems aids in maintaining overall health and defending against pathogens.
