The
Difference Between Innate Immunity And Adaptive Immunity
You may
not be aware of this but your immune system has two distinct elements that make
it up. Each one of these elements has its own purpose and its own way of
working. We believe that it is important for you to understand these
differences to be aware of how your immune system functions.
Innate
and Adaptive Immunity
The two
categories of your immune system are called the “innate immunity” and “adaptive
immunity”. They are both essential for fighting off potential diseases and also
for preventing them from getting a foothold. It is very important that you
understand how they function so that you are aware of how your immune system
protects you from disease.
Innate
Immunity
Your
first line of defense is your innate immunity. It stops pathogens making their
way you’re your body in the first place. Your innate immunity does not go after
any particular type of pathogen.
Often the
innate immunity is non-specific in nature because it will target anything that
it discovers in your body that should not be there rather than chase after a
specific type of pathogen. Two significant parts of your innate immunity that
you will be familiar with are your skin and your hair.
Your skin
is vital as it provides a barrier for your body to the outside world. The skin
does a great job in keeping out things that want to get in. Your hair also
performs a vital role as it will trap different types of micro organisms and it
is essential that you wash it often so that it is always clean.
If you
have long hair then never put it into your mouth and chew it or bite it. You
never know what kind of bad microorganisms your hair has trapped and you do not
want these in your mouth. There are a lot of other internal parts to your
innate immunity and one of these is mucus.
Similar
to your hair, mucus will trap micro organisms as well. It will trap harmful
bacteria before it is able to reach your respiratory system. Mucus is
responsible for you developing a cough prior to getting sick.
Adaptive
Immunity
You have
a number of cells that will try to eliminate any foreign body that they believe
should not be there. Your adaptive immunity works in a different way in that it
responds with the discovery of a threat that has already begun to become a
problem for you.
This
element of your immune system will specialize in eliminating sickness using a
variety of methods. This could be opening up a membrane or simply taking it and
flushing it out of your system.
The most common
examples of your adaptive immunity are T cells and B cells. These cells have
memories and will recognize foreign bodies that they have fought in the past.
This is great because they will know how they will need to fight against them
if they appear again. When these cells see a threat they try to identify it so
they know what to do to eliminate it.
