Innate immunity forms the first line of defense (skin and mucous membranes) and second line of defense (defensive cells, inflammation, fever)
The function of innate immunity is to block invading microbes into destroying those which succeed in penetrating the body.
Example of innate immune system
- swelling occurs in the area where you have scratched (Inflammation)
Adaptive immunity is known as the third line of defense (T cells, B cells and antigen presenting cells). Another name for adaptive immunity is acquired immunity.
- An example of adaptive immune response is a liver transplant from a donor to the recipient ( T cells or B cells)
