The body
defense system is made up of two parts, the innate or non specific and the
adaptive or specific immune system respectively.
INNATE /NON SPECIFIC IMMUNE SYSTEM
This is the
body’s first line of defense, it is made up of macrophages and neutrophils that
engulf and kill foreign pathogens without the need for antibodies.
The innate
immunity also comprises anatomical features which act as barriers to infections
and includes, skin tears, saliva and cilia.
The innate
immune system includes defense that for most parts are present in the body and ready
to be mobilized upon infection.
It is not
antigen specific and therefore react equally well to different types of
microorganisms.
Innate immunity
is antigen independent.
The innate
response does not demonstrate Immunological memory.
ADAPTIVE IMMUNE SYSTEM
This is the
body second line of defence, it involves the use of antibodies which are
specific proteins that bind to antigen to induce cell mediated response, making
the cell to recognize foreign invaders and destroy them.
This body
mechanism requires time to react to an invader.
Adaptive
immune system demonstrates a higher degree of specificity and reacts only with
the organism that induces the response and is therefore antigen specific.
In adaptive
immunity is antigen dependent.
Adaptive
response demonstrates immunological memory. This means that it remembers it has
encountered and invader in the past and react more rapidly to a second
infection by the organism.
