How stress influences physical disease
• Immune system protects body against stress-related diseases

The immune system
• Protects body against invasion of foreign material– Viruses– Bacteria– Foreign tissue (e.g. heart transplant)
• Removes damaged cells

Immune system disorders
• Immune deficiency– AIDS
• Acquired Immune Deficiency Syndrome
– Caused by the HIV virus• Human Immunodeficiency Virus• Destroys the T-cells in the immune system
• HIV destroys immune system - AIDS - vulnerable to bacterial, viral, and other diseases

Transplant rejection
• Immune system tries to fight the foreign tissue
• Drugs given to reduce effects of immune system
