Answer:
Parts of the immune system
The main parts of the immune system are:
white blood cells
antibodies
complement system
lymphatic system
spleen
bone marrow
thymus.
White blood cells move through blood and tissue throughout your body, looking for foreign invaders (microbes) such as bacteria, viruses, parasites and fungi. When they find them, they launch an immune attack.
Antibodies
Antibodies help the body to fight microbes or the toxins (poisons) they produce. They do this by recognising substances called antigens on the surface of the microbe, or in the chemicals they produce, which mark the microbe or toxin as being foreign. The antibodies then mark these antigens for destruction. There are many cells, proteins and chemicals involved in this attack.
Complement system
The complement system is made up of proteins whose actions complement the work done by antibodies
Lymphatic system
The lymphatic system is a network of delicate tubes throughout the body. The main roles of the lymphatic system are to:
manage the fluid levels in the body
react to bacteria
Bone marrow
Bone marrow is the spongy tissue found inside your bones. It produces the red blood cells our bodies need to carry oxygen, the white blood cells we use to fight infection, and the platelets we need to help our blood clot.
Thymus
The thymus filters and monitors your blood content. It produces the white blood cells called T-lymphocytes
