The lymphatic system helps your body to fight infections.
It is made up of...
- a network of narrow tubes (the lymphatics) that carries lymph fluid all around the body. The fluid contains white blood cells (lymphocytes) that fight infection
- glands called lymph nodes. You have groups of these pea-sized glands in your neck, armpits, groin, chest and abdomen (belly). The nodes make and store the lymphocytes. They also act as filters, trapping and removing germs so that they can’t do you any more harm
- other organs such as the spleen, bone marrow and tonsils.
