The immune system protects the body against illness and infection caused by bacteria, viruses, fungi or parasites. It is really a collection of reactions and responses that the body makes to damaged cells or infection.ancer can weaken the immune system by spreading into the bone marrow. The bone marrow makes blood cells that help to fight infection. Weakening of the immune system happens most often in leukaemia or lymphoma.
The human immunodeficiency virus (HIV) infects cells of the immune system, destroying or impairing their function. Infection with the virus results in progressive deterioration of the immune system, leading to immune deficiency. The immune system is considered deficient when it can no longer fulfil its role of fighting infection and disease.
