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
Disease symptoms are usually your body’s way of fighting the pathogen (raising temperature to make your body a not hospitable environment, inflammation means cells are rushing to the problem to fight it off)
And yes, a good immune system basically has the necessary number of immune cells in a healthy environment to fight the virus or bacteria easily enough before it multiplies and makes more trouble, thus the symptoms becoming more severe.
