What is innate immunity and its role in host defense?
Click to see answer
Innate immunity, also known as Natural or Native Immunity, is the first line of defense against infections. It blocks microbial invasion through Epithelial Barriers, destroys many microbes that enter the body, and helps eradicate infections. It provides essential protection during the delay of the Adaptive Immune System, which requires antigen stimulation and takes several days to develop.

Innate immunity, also known as Natural or Native Immunity, is the first line of defense against infections. It blocks microbial invasion through Epithelial Barriers, destroys many microbes that enter the body, and helps eradicate infections. It provides essential protection during the delay of the Adaptive Immune System, which requires antigen stimulation and takes several days to develop.
How does innate immunity interact with the adaptive immune system?
Innate immunity instructs the Adaptive Immune System to respond to different microbes effectively. It plays a crucial role in guiding the adaptive response, ensuring that the body can combat specific pathogens effectively after the initial innate response.
What additional functions does innate immunity serve beyond infection control?
Beyond infection control, innate immunity is a key participant in the clearance of dead tissues and the initiation of repair after tissue damage. This highlights its importance not only in defense against pathogens but also in tissue maintenance and healing.
