The lymphatic system is the interconnected network of organs and vessels between body tissues and organs by which lymph circulates throughout the body. Lymph is colorless fluid that continuously bathes the cells of the body, and is circulated around the body in order to remove excess fluid and harmful materials from interstitial spaces (body tissues outside the blood vessels). Lymph contains a type of white blood cells called lymphocytes as well as macrophages, they are the infection-fighting components of the lymphatic system.
