Question

Will the food pass through the elementary Canal if we are hung upside down

Answer 1

there is gravitational force. but more than that ,the main function -the peristalic movement .it is where the mucles in the body pushes the food down and down for  more simplification.
thus the food will pass through the elementary canal even if we are hung upside down.

Answer 2

Hi dear

Yes, the food will pass through the alimentary canal if we are hung upside down. As muscle contractions take place in our body through peristalsis through the alimentary canal the esophagus smooth muscles pushes the food down no matter we are hung upside down.
