Question

food does not come out even if we are hanging upside down

Answer 1

this is because of our peristaltic movement happening in the oesophagus which regulates the food in the stomach

if we are hanging upside down then food does not come out because....
● food only comes out from our abdomen only by reverse peristalsis.
●If we are hanging upside down then reverse peristalsis does not occur in the oesophagus of our body.
●This is the reason of your question.
