Immune system

Transcript

Immune cells are produced in the bone marrow. They move rapidly through the body in the blood to get to the sites of infection, where they pass into tissues and then move between individual cells. They return to the blood by travelling via the lymphatic system. Lymph nodes are special sites where they collaborate to fight infection.
