6. The Mains Parts of the Immune System
● White Bloods Cells: is a a key players in your immune system, made in your bone marrow and part
of the lymphatic system. They move through blood and tissue through your body, they look for
foreign invaders (microbes) such as bacteria, viruses, parasites and fungi. When they find them, they
launch an immune attack.
● Antibodies: help the body fight microbes or the toxins (poisons) they produce by recognising
substances called antigens on the surface of microbe, or in the chemicals they produce, which mark
the microbe or toxin as being foreign,
● Complement systems: made up of proteins whose action complement the work done be
antibodies.
● Lymphatic system: main roles is to manage the fluid levels in the body, react to bacteria, deal with
cancer cells, deal with cell products that otherwise would results in disease or disorders, and absorb
some of the fats in our diet from the intestine.
● Spleen: a blood- filtering organ that removes microbes and destroys old or damaged red blood cells.
● Bone Marrow: the spongy tissue found inside your bones. It produces the red blood cells our bodies
need to carry oxygen and the white blood cells we use to fight infection also the platelets we need to
help our blood clot.
● Thymus: filters and monitors your blood content and it produces the white cells called T-
lymphocytes.
