Difference between Innate and Adaptive Immunity

Serial no.	Features	Innate immunity	Adaptive immunity
1.	Definition	The resistance to microbial infection that an individual passes by virtue of its genetic makeup.	The Resistance acquired by an individual during its life.
2.	Activity	Always present	Normally silent
3.	Specificity	Non-specific	Always specific
4.	Response   time	Immune response in minutes	Takes days to generate response
5.	Diversity	Diversity is limited	Adaptive immunity is more varied
6.	Potency	It has a limited and lower potency.	It has highly potent immune response.
7.	Immunological memory	Absent	Present
8.	Heritance	Innate immunity is heritable.	Passive acquired immunity is heritable from mother to neonates for a brief period after death.
9.	Origin	It is present before the first exposure to microbial antigen.	Develops during lifetime following the antigenic exposure.
10.	Components	1. Anatomical /Physiological barrier like skin mucous membrane, temperature, pH, chemicals. 2. Cells: Phagocytes (Macroccytes, 3.Mcrophages, Neutropils), NK. 4.Complement 5. Normal resident flora.	1.T cell 2.B cell 3.Classical component pathway 4. Antigen presenting cells 5. Cytokines etc.
11.	Classification	Innate immunity is classified into specific and non specific immunity.	Adaptive immunity is classified into active and passive immunity.
