The lymphatic system and the circulatory system often work in conjunction with each other to form a united front against disease and other bodily ailments.

Excess tissue fluids are returned to the bloodstream via the lymphatic system’s vessels, draining approximately 15% which has not been previously returned via the capillaries.


The lymphatic system is made up of lymph (fluid) and lymph nodes (filters for the fluid) and a network of vessels that permit travel both throughout the body and throughout the bloodstream in order to pick up where much of the body’s circulatory system has left behind. The lymphatic system is very much like the collector of small bits after the circulatory system has come through and taken what it can carry.

The lymphatic system also joins forces with white blood cells in the fight against disease and other foreign material within the body.
