The primary function of lymph nodes is to filter lymph, the extracellular fluid that has leaked from blood capillaries, and return it to circulation. This process helps maintain fluid balance within the body.
Understanding Lymph Node Function
Lymph nodes play a crucial role in the body's immune and circulatory systems. Here's a breakdown of their main function:
-
Filtration: Lymph nodes act as filters for lymph, a clear fluid containing white blood cells that circulates throughout the body.
-
Fluid Balance: By filtering lymph and returning it to the bloodstream, lymph nodes help maintain proper fluid balance in the body. This prevents life-threatening fluid imbalances. As stated by reference "Function of Lymph Nodes The primary function of lymph nodes is to filter lymph, the extracellular fluid that has leaked from blood capillaries, and return it to circulation. This filtration process helps maintain fluid balance and prevents fluid imbalance that could be life-threatening".
In essence, lymph nodes contribute to the overall well-being of the body by filtering fluids and maintaining balance.
