The Lymphatic System | Health | Biology | FuseSchool

Did you know your body has its own version of a sewer system, for removing unwanted toxins, waste and excess water from the body? This is called our lymphatic system.

Like our blood circulation, the lymphatic system is made up of millions of little vessels that branch all around our body. But whereas arteries and veins carry blood, the lymphatic vessels are much, much finer and carry a colourless fluid called lymph.

Our lymphatic system has 3 main duties:
(1) It contains white blood cells called lymphocytes, which are used to fight infection;
(2) It acts as a one way drainage system, transporting fluid from body tissues into the blood circulation;
(3) It gets rid of waste products produced by cells.
