ELI5 - what is the body doing during the "ahhh" phase of "ahh-choo"?

Inhaling. you can't sneeze if you don't have any air in your lungs. When you go "ahhh" you're breathing in as much air as you can so when you go "choo" you have some air pressure to clear out the slime, mucus and irritants your body doesn't like.
