During an infection, or if cancer is present, large amounts of this waste material can build up in the nodes, and many kinds of normal immune system cells take up residence there, causing the nodes to swell. There, damaged cells, infectious organisms, and cancer cells are separated out and destroyed. Nodes are situated at key points on the vessels and serve as collection centers.
Some of the waste-laden lymph returns to the bloodstream, but the rest enters the lymphatic vessels – tubes that extend throughout the body, much like blood vessels do. It also contains white blood cells, which help fight infections.
It performs a variety of roles, including carrying oxygen and other nutrients to cells and carrying away waste products like carbon dioxide.
