I know that stuff like mucus and skin can keep germs physically away from the body, but why does a good immune system keep you healthy?
Can a strong immune system make it so that you might not even feel symptoms of a disease in the first place, or is it just a matter of recovery and fighting off the illness?
In: Biology
The immune system is very complex with a multitude of different components at play. The core gist that everyone should know is what antibodies are. An antibody is a protein that almost works like a lock and key. The lock is the invader and the key is the antibody itself and when they match, that invader is marked for death. I’m not going to get into the entire pathway but know that there are molecules (interferons, interleukins if you are interested) that aid in propagating the bodies “make antibodies” mode. So it would make sense then with more of these components at your disposal, that you would get sicker less and for shorter amounts of time.
