Lymphatic system

Definition:

The lymphatic system is an extensive network of vessels that passes through almost all our organs and tissues. It's a drainage system that allows the movement of a lymph, a fluid containing white blood cells called lymphocytes, which fight infection, making it a vital part of our immune system. Lymph circulates through the body in a similar way to blood, and is transported from body tissues into the blood circulation. The lymphatic system maintains the balance of fluid between the blood and tissues (fluid homeostasis), helps defend against bacteria and other intruders, and facilitates absorption of fats and fat-soluble nutrients in the digestive system.
