The lymphatic system

The lymphatic system is a network of vessels, organs, and tissues that help your body defend against infections and maintain fluid balance. It transports a clear fluid called lymph, which contains immune cells that identify and fight germs, viruses, and other harmful substances. Key parts include lymph nodes, where immune cells gather, and organs like the spleen and thymus, which support immune function. The system also helps drain excess fluid from tissues, returning it to your bloodstream. Overall, it plays a vital role in protecting health and keeping your body's environment stable.
