Answer:
Innate immune system is the first immune system in the body. It is usually described as the first line of defense. It is not learned or acquired from the environment.
The two sensory systems of innate immune response are:
- DNA sensing innate response.
- Pattern recognition receptors (PRRs) mediated microbe sensing.
Three effector actions are:
- Y shaped proteins on the epithelial walls.
- All blood cells activation.
- Phagocytosis by macrophages.
