10 Questions
What is the primary function of the immune system?
To recognize and eliminate foreign cells
What is the main characteristic of the innate immune system?
It is non-specific and recognizes anything that is not self
How does the adaptive immune system respond to infections?
It changes in character to fight specific infections
What is produced by the adaptive immune system to fight specific infections?
A specific antibody that fights a specific infection
What is the main difference between the innate and adaptive immune systems?
The innate immune system is non-specific, while the adaptive immune system is specific
What would happen if foreign organisms were allowed to spread unchecked in the body?
Death would result
What is a key feature of the innate immune system?
It recognises anything that is not self
What happens to the adaptive immune system following an infection?
It changes character to make it more capable of fighting the infection
What is the relationship between the adaptive immune system and foreign cells?
The adaptive immune system remembers foreign cells
What is a key difference between the innate and adaptive immune systems?
The innate immune system is non-specific, while the adaptive immune system is specific
Study Notes
Immunology and the Immune System
- Immunology is the study of the immune system that protects us from foreign organisms and agents.
- The immune system has three main functions: recognising, eliminating, and destroying foreign cells, as well as remembering them.
Components of the Immune System
- The immune system consists of two main components: the innate immune system and the adaptive immune system.
Innate Immune System
- The innate immune system is present from birth and is non-specific, meaning it recognises anything that is "not self".
- It provides immediate defense against infections and is the first line of defense.
Adaptive Immune System
- The adaptive immune system changes in character following an infection to make it more capable of fighting the infection.
- It is specific, meaning a specific cell or agent of the immune system (e.g. an antibody) is produced to fight a specific invasion.
- The adaptive immune system allows for long-term immunity to specific pathogens.
