,The Concept of Immunity
• Immunity or resistance is the ability to ward off damage
or disease through our defenses. Vulnerability or lack of
resistance is termed susceptibility.
• The two general types of immunity are
• (1) innate and (2) adaptive.
• Innate immunity is the body's first line of defence
against pathogens. It is general and non-specific, which
means it does not differentiate between types of
pathogens.
• Adaptive immunity is a type of immunity that is built up
as we are exposed to diseases or get vaccinated.
, INNATE IMMUNITY:
• Innate immunity is also known as non specific
immune system comprises the cells and the
mechanisms that defend hosts from pathogen in
a non specific manner. It consists physical
barrier (skin, mucous membrane) and chemical
barrier (gastric juice, lysozymes). It provides
immunity by first and second line of defense.
