What is innate immunity Class 12?
Innate immunity, also called inborn immunity, is inherited from parents and is present by birth. It is not specific, it acts the same for all intruders entering the body. Protection is provided in the form of barriers in this type of immunity.
How is innate immunity activated?
The cells and molecules of innate immunity are rapidly activated by encounter with microbes or other “danger signals.” The rapidity of the response is essential because of the fast doubling time of typical bacteria.
What is innate immunity Class 9?
Innate immunity refers to the body’s defence system. This immunity helps us by providing the natural resistance components including salivary enzymes, natural killer cells, intact skin and neutrophils, etc. which produce an initial response against the infections at birth prior to exposure to a pathogen or antigens.

Is innate immunity present at birth?
Medzhitov and Janeway defined innate immunity as a system of rapid immune responses that are present from birth and not adapted or permanently heightened as a result of exposure to micro-organisms, in contrast to the responses of T and B lymphocytes in the adaptive immune system [6-8].
