What is the lymphatic system made of?
The lymphatic system, which is a part of your body’s defense system, contains lymph vessels and lymph nodes. • Lymph vessels are thin tubes that carry a fluid called lymph and white blood cells. • Lymph vessels lead to small, bean-shaped organs called lymph nodes. Lymph nodes are found near your breast, under your arm, above your collarbone, in your chest, and in other parts of your body. • Lymph nodes filter substances in lymph to help fight infection and disease. They also store disease-fighting white blood cells called lymphocytes.
