This is what keeps us alive and healthy, and without it we would not be able to survive.

The immune system fights aggressive germs or germs to ensure that they do not remain in our body. It also contains chemicals and toxins.

The immune system monitors all the germs he has ever battled. This means that when an unwanted microbe enters the body, the immune system can recognize it and knows to attack it. It not only recognizes it, but it can also attack it quickly before it affects our body.

So, for example, when we have a cough, our immune system learns how to fight it, but it can take a week or two. Then when our body comes in contact with the same germs again, it can detect them immediately and fight them before attacking our body.
