lymphatic system
This system's funtions are (1) to transport tissue fluid to the blood vessels, and (2) to protect the body by removing foreign material such as bacteria from the lymphatic stream and by serving as a cite for lymphocytes "policing of body fluids and lymphocyte multiplication. It is a one-way system that carries lymph only towards the heart.
