Why does the immune system react in that way; what causes it to act irregularly when it shouldn’t?
In: 1
The immune system components can’t text each other, they are too small to have cell phones. So, they communicate through chemicals. One chemical means “I’m in trouble, send help”. The reaction varies from person to person, this also how allergies work. However, the cytokine storm is a help message that gets too much response. This starts to cause damage, and the damage causes more calls for help. This is an example of positive feedback, and can be harmful to the person.
