The immune system is what protects an organism, in this case our human body, from invasion by viruses, bacteria, germs, parasites, toxins and all kind of pathogen microorganisms.
Our immune system assist us in staying healthy by preventing illness to spread in our body. Put simply, our immune system keeps us alive. As soon as the immune system stops working properly or is overload, we get sick and may even die.
The human body is an ideal ground for many germs and they definitely would love to get inside and attack the body. It is the immune system job to keep them out. But if they get in, it is also the immune system duty to find and destroy the invaders.
The skin is the first obstacle these invaders encounter, which offers an excellent guard for the body. The skin is not easy to go through and is made of an assortment of substances that are risky to the invaders. Holes such as the eyes, the mouth and the nose, which appear less difficult to invade have some defence too. They are protected by liquids that can arrest devious invaders.
As you can see, immune systems are constantly busy and on the lookout for pathogens that are trying to harm our body. It's a difficult task because first of all the immune system has to distinguish and remember millions of different enemies.
Then, it must make the right defence like secretions and cells to match up with and wipe out each one of them. This is done with the help of a complicated communication network. Millions of organized cells get together and exchange information back and forth. Once 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 critical since without this aptitude the immune system can not have a clue of which organisms to assault or not. This is done with the help of "marker molecules". When the immune system defenders encounter organisms transporting markers that say "foreign", they directly launch an attack. The faster the response the better they can eliminate the invaders.
