The lymphatic system is a complex network of vessels, tissues, and organs that plays a crucial role in maintaining immunity and fluid balance in the body. It consists of lymph, lymph nodes, lymphatic vessels, the spleen, thymus, and tonsils. Lymph is a clear fluid that circulates through the lymphatic vessels, transporting immune cells, proteins, and metabolic waste. Lymph nodes, small bean-shaped organs located along the lymphatic vessels, act as filters, capturing and destroying pathogens and damaged cells.
