Introduction
to Immune System
Before going into the cause of illness and disease, we need to know
something about our immune system.
Immune system is an important network of cells, tissues and organs that
work together to defend the body against attack by foreign invaders or enemy
which are primarily germs which are very tiny, and also infection causing
organism such as parasites, bacteria, viruses and fungi. The human body provides an ideal environment
for many microbes, and when they are able to break in, due to low immunity,
they break into human body through various parts of our body. It is the Immune systems job to keep these
critters out of the body, failing which, if they enter the body, the job of the
immune system to seek out and destroy them completely.
Our Immune system is amazingly complex. It can even recognize and remember millions
of different enemies, and it can produce secretions and cells to match up with
and wipe out each one of them. The
secret of it’s success is its elaborate and dynamic communications
network. Millions and millions of cells,
organized into sets and subsets, gather like clouds of bees swarming around a
hive and pass information back and forth.
You need to know that every second of your life, you are under attack
from bacteria, viruses, spores and many more live stuff that are foreign and
wants to enter your body and use your body’s resources for sustenance and it is
the immune system that protects you from all these microscopic invaders without
the immune system you would die in no time.
Though this might very simple but what goes on inside the body to
protect your is very complex.

You can know whether you immune
system is working properly or whether your immune system is strong but
answering a simple questions. Do you get
sick quite often? Do you take sick days
off from work quite often? Are you fatigued day in and day out? Do you have frequent colds and sore
throat? if yes to any of these, then
your immune system is weak and trying to cope up with many challenges in the
body.
