Study Notes
Infection
- Infection: multiplication of pathogenic microbes in living organisms
- Wound: tearing of tissues caused by injury or burns
Immunity
- Immunity: an organism's ability to combat foreign substances (like microbes, toxins)
- Innate Immunity: a defense system present from birth, combating various foreign substances equally
- Acquired Immunity: immunity developed over time after exposure to a particular microbe
Inflammation
- Inflammation: a rapid and localized response by the body in response to a broken barrier by microbes, presenting with symptoms like redness, heat, swelling, and pain.
- Diapedesis: white blood cells moving through blood vessel walls to damaged areas
- Inflammatory mediators: substances released by injured tissues to attract phagocytes
Phagocytosis
- Phagocyte: white blood cells capable of phagocytosis
- Phagocytosis: engulfing and digesting foreign particles by certain white blood cells
Antigens and Antibodies
- Antigens: foreign substances that trigger an immune response
- Antibodies: special substances produced by the immune system to target specific antigens
