Specific Resistance Flashcards
the third line of defense and the body’s ability to defend itself against specific foreign material or organisms is called
immunity
3 requirements are:
- self vs non-self
- 2nd encounter produces even more vigorous response than the initial encounter
- able to respond to billions of potential pathogens
- SPECIFICITY
- MEMORY
- VERSATILITY

3 essential steps of the immune system response:
- caught on the radar
- man your battle stations
- fire all weapons
- recognition of the invader
- activation of the system
- response to the invader
