The
lymphatic system is a defense system for the body. It filters out organisms that cause disease, produces
white blood cells, and generates disease-fighting
antibodies. It also distributes fluids and
nutrients in the body and drains excess fluids and protein so that
tissues do not swell. The lymphatic system is made up of a network of vessels that help circulate body fluids. These vessels carry excess fluid away from the spaces between tissues and organs and return it to the bloodstream.
