What would happen if the immune system failed to protect us from other organisms or agents?
- Our bodies would change to accommodate the foreign cells
- We would experience a gradual decline in health
- We would die (correct)
- We would become immune to all diseases
What is the primary function of the innate immune system?
What is the primary function of the innate immune system?
- To adapt to new infections and change its character
- To recognise and eliminate anything that is 'not self' (correct)
- To remember and eliminate foreign cells
- To produce specific antibodies to fight infections
What is a characteristic of the adaptive immune system?
What is a characteristic of the adaptive immune system?
- It has no memory of previous infections
- It is non-specific and recognizes anything that is 'not self'
- It is present from birth and does not change
- It produces specific cells or agents to fight specific infections (correct)

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
