The immune system is the system that defends an organism, such as our human body, from invasion by bacteria, viruses, germs, parasites, toxins and all kind of pathogen microorganisms.
Our immune system helps us to stay healthy by preventing infection to spread in our body. Let just say that our immune system keeps us alive. The minute the immune system stops working properly or is overload, we become ill and can even die.
For many germs, the human body is an ideal ground and they definitely would like to break in and invade the body. It's the immune system job to keep them out. But if they do manage to get in, it is also the immune system duty to look for and destroy the invaders.
The first barrier these invaders encounter is the skin, which offers a good guard for the body. The skin is not easy to go through and is made of an assortment of substances that are dangerous to the germs. Openings such as the eyes, the mouth and the nose, which appear easy to invade possess some defence too. They are protected by fluids that can arrest mean invaders.
As you can see, immune systems are constantly busy and on the lookout for pathogens that are trying to heart our body. It's a difficult task because first of all the immune system has to recognize and remember millions of various enemies.
Secondly, it must make the proper defence like secretions and cells to match up with and wipe out each germ. This is done with the assistance of a complex communication network. Millions of organized cells meet and exchange information back and forth. As soon as the immune cells receive the alert, they start creating powerful chemicals. But the fantastic ability to distinguish the body' s own cells and the foreign cells is the key to a healthy immune system.
This is important because without this aptitude the immune system will not have a clue of which organisms to assault or not. This is done with the assistance of "marker molecules". When the immune system defenders encounter organisms transporting markers that say "foreign", they immediately send an attack. The faster the response the better they can get rid of the germs.
