Abstract

The immune system can be construed as interesting , complex , and intricate mechanism . The system works all through the body however there are definite sites where the immune system cells are sorted out into precise structures . It is the job of the immune system to keep millions of unwanted microbes , bacteria , parasites , toxins , and viruses out of the human body or , falling short from that to search for and annihilate them

The Immune System

Inside every human body

is an astonishing defense mechanism termed as the immune system . It is designed to protect humans against millions of microbes , bacteria , parasites , toxins and viruses that would find it enticing to attack the human body . The immune system is a complex of tissues , organs , and cells that work together to shield the body against assaults by the said foreign organisms . Because the human body presents a perfect environment for countless microbes , they may undertake to break in to it (National Institute of Allergy and Infectious Diseases [NIAID] National Cancer Institute [NCI] , 2003 ,

.1 . Therefore , it is the job of the immune system to keep them out , or when a foreign organism has made a way into the body , the immune system searches for it and annihilates it . However , when the system is crippled or strikes an unintended target , it can let loose an outburst of diseases , including arthritis , AIDS , or allergy (NIAI NCI , 2003

Viruses and bacteria are the organisms most frequently responsible for attacking human bodies . Bacteria may live independently or dependently by living on or inside other organisms . Either way , a number of bacteria that have human hosts generate poisons that harm the body (Noble Foundation , 2008 . Viruses , in contrast , are not capable of reproducing on their own as they need a host cell . Such being the case , the viruses hijack human body cells , and trap them into generating new viruses that can then attack other cells . More often than not , the host cell is damaged during the course (Noble Foundation , 2008

The immune system can be construed as interesting , complex , and intricate mechanism . It can remember and recognize millions of diverse enemies it can also create cells and secretions to wipe out and match up with each one of the said enemies . The secret of the system 's accomplishment is its dynamic and sophisticated communication coordination . Millions of cells , classified into divisions and sets congregate like clouds of bees swarming around a hive and pass information from side to side . Once alarm is received by the immune cells , they go through tactical changes and commence to produce potent chemicals . The chemicals then allow the cells to control their own behavior and growth , get hold of their members , and direct new enlist cells to problem spots (NIAID NCI , 2003 ,

Immunity can be artificial or natural , acquired or innate , and passive or active . Active natural immunity mechanism affects a long-term immunity to the body . When in contact...
