how does the food reaches to the small intestine when we sleep at night just after having dinner, which is against the gravity as the food has to go parallel to the earth surface?
In: Biology
It’s a process called peristalsis. Basically, your stomach muscles will push food into your small intestines. It’s not like there’s simply a gate at the bottom of your stomach that food drops through because of gravity.
Peristalsis is the same reason that you can eat even when you’re standing on your head.
