Examples include antigens of bacteria, viruses, toxins, cells

, and foreign blood or tissues from another person or species. When the immune system detects an antigen, it is responsible by producing proteins called antibodies that destroy harmful substances.

People who have been removed spleen in their acquired immunodeficiency, and a higher risk of infection by certain bacteria, spleen, normally help fight. Patients with diabetes are also prone to increased risk for certain infections. With age, the reduced effectiveness of the immune system to some extent. Immune system tissues (particularly lymphoid tissue such as the thymus) shrink, and the number and activity of white blood cells drop. .
