The immune system is the system that defends an organism, in this case our human body, from invasion by bacteria, viruses, parasites, germs, toxins and all types of pathogen microorganisms.
Our immune system helps us to stay healthy by avoiding infection to spread in our body. Put simply, our immune system allows us to stay alive. As soon as 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 certainly would like to break in and invade the body. It's the immune system work to keep these germs out. But if they succeed in getting in, it is also the immune system duty to seek and demolish the invaders.
The first barrier these invaders encounter is the skin, which provides a great guard for the body. The skin is hard to go through and is made of an array of substances that are dangerous to the invaders. Openings like the eyes, the mouth and the nose, which seem less difficult to invade possess some defence too. They are protected by fluids that can arrest sneaky invaders.
Obviously, immune systems are always busy and looking for pathogens that are trying to heart our body. It is not an easy task because first of all the immune system has to recognize and keep in mind millions of different enemies.
Then, it has to produce the right defence like secretions and cells to match up with and wipe out each germ. This is done with the assistance of an elaborate communication network. Millions of organized cells meet and exchange information back and forth. As soon as the immune cells receive the alert, they start producing 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 since without this ability 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 come across organisms transporting markers that say "foreign", they instantly launch an attack. The faster the response the better they can get rid of the invaders.
This website was built with the intention to give information that could help the reader to get at least a glimpse of the complexity and the extraordinary system working non stop for us, and that most of the time we are not even aware of. By learning about our immune system it will help you to be healthier and live longer.
