1.2 The Lymphatic System
Self-Check
Lymph vessels are closely associated with the capillaries of the cardiovascular system. Fluid that escapes from the cardiovascular capillaries forms part of the interstitial fluid. Some of this fluid is collected in the
lymphatic capillaries and is eventually returned to the blood.
The lymphatic system also works with the white blood cells to protect the body against infection. White blood cells, called lymphocytes, mature in the lymph nodes, which are the glands found throughout the lymphatic system. The lymph nodes
also contain macrophages, which trap and destroy bacteria that are circulating within the body.
