Compare and contrast by saying how are they alike and how are they different.
Take at least 4 of the following points into consideration:
1. Length of time for protection against pathogens
2. Time taken for cells/barriers to exert their effects on pathogens
3. Renewal of defence structures by the body (e.g. cells, barriers)
4. Effect of age on defence systems
5. Movements of cells involved in defence
Compare and contrast the effectiveness and efficiency of nonspecific immune defences with specific immune defences?
THANK YOU!
