Study Notes
Innate Immunity
- The innate immune system is the body's first line of defense against infection.
- It reacts immediately to threats, unlike the adaptive immune system which takes longer to respond.
- It consists of physical barriers, chemical barriers, and cellular components.
Physical Barriers
- Skin: Composed of tightly packed epithelial cells that form a barrier to invading microorganisms.
- Mucous membranes: Line the conjunctivae, digestive, respiratory, and urogenital tracts. They produce mucus, saliva, and tears that trap and flush out pathogens.
- Normal flora: Compete with pathogens for attachment sites on epithelial cells and necessary nutrients.
Immunology
- The study of the immune system and how it defends the body against infection.
- It also investigates the consequences of immune responses, both beneficial and harmful.
- Immunology focuses on the physiological mechanisms behind immune responses.
