Immunity or the ability to resist the injury caused by microorganisms and their products is inbuilt within us.

. Immunity is natural, that is everyone is born with a general type of protection. For example, the external barriers of the body, like the skin and mucous membranes.

. Immunity can also be adapted; it develops throughout our lives. Adaptive immunity involves the white blood cells or lymphocytes and develops as we are exposed to diseases or immunized against diseases through vaccination.

. Passive immunity is derived from other sources. Though it lasts for a short time, it does have an impact on the body. For example, antibodies in a mother's breast milk provide immunity for the baby and the food we eat has an impact on our immune system.
