Immunity
is the state of sensitivity of the organism to one or more substances with
antigen proprieties ("non-self" - foreign body) and is characterized
by the development of an immune response in contact with an immunogenic agent.
After the
type and amount of antigen, by the way of penetration of the antigen and by the
quality of genetic and physiological status of the body, immunity has various
forms.

Immunity
can be classified into two broad types: innate and acquired. Innate immunity
is the body's very own inborn or natural resistance power against a wide range
of germs. Examples of innate immunity are as follows: cough reflex, mucus,
skin, stomach acid and enzymes in tears and skin oil. Innate immunity may be in
the form of protein chemical, and is known as innate humeral immunity. Acquired
immunity again falls into two categories: naturally acquired and artificially
acquired. Naturally acquired immunity is acquired by the body as a response to
an invasion by some disease causing agent and the invasion is not deliberate.
Artificially acquired immunity is the deliberate exposure of the body to
disease causing agents, and it occurs mainly through vaccination.
The
naturally acquired immunity or the artificially acquired immunity may be both
active and passive. Passive immunity consists in antibodies produced in and
transferred from another person's or animal's body. For instance, babies are
born with passive immunity or antibodies transferred from the mother's
placenta. Passive immunization is a long-lasting protection in the form of
antiserum injections which bear antibodies produced in another body. Precaution
against hepatitis and tetanus are instances of passive immunization.
So To
keep a healthy body .You must maintain a good immunity. It is very much
required for a healthy and fit body .And as you know that a healthy body can give
you a successful life.
