林巴 (Lín bā) refers to the lymphatic system, a crucial part of the human immune system. It consists of a network of vessels, nodes, and organs that help transport lymph, a fluid containing infection-fighting white blood cells. The lymphatic system plays a vital role in maintaining fluid balance in the body and protecting against infections. The lymphatic system includes structures such as 淋巴结 (lymph nodes), 脾脏 (spleen), and 扁桃体 (tonsils). These components work together to filter harmful substances and support the body's defense mechanisms. Proper functioning of the lymphatic system is essential for overall health and well-being.
