Study Notes
Immunology Overview
- Immunology is the study of the immune system, which protects us from other organisms/agents that could cause death if left unchecked.
Immune System Functions
- Recognizes foreign cells
- Eliminates foreign cells
- Destroys foreign cells
- Remembers foreign cells
Immune System Components
Innate Immune System
- Present from birth
- Non-specific, recognizing anything that is "not self"
Adaptive Immune System
- Develops during our lives in response to infection
- Adapts to become more capable of fighting infections
- Very specific, producing specific cells or agents (e.g. antibodies) to fight specific invasions
