Description: Lymph is a clear fluid that circulates through the lymphatic system, an essential component of the human body’s immune system. This fluid, which is primarily composed of water, proteins, salts, and white blood cells, plays a crucial role in defending the body against infections and diseases. Lymph originates in the body’s tissues, where it filters through lymphatic capillaries, collecting cellular waste, toxins, and other waste products. As lymph moves through lymphatic vessels, it passes through lymph nodes, where it undergoes a filtration process that helps remove pathogens and harmful cells. This process not only contributes to the cleansing of the fluid but also activates immune cells, thereby strengthening the body’s immune response. Thus, lymph not only acts as a transport medium for nutrients and waste but is also fundamental in maintaining homeostasis and overall health. Its circulation is driven by muscle contractions and pressure from the venous system, distinguishing it from blood, which is pumped by the heart. In summary, lymph is a vital component of the lymphatic system, essential for immunity and waste elimination in the human body.
