Question

Forces affect motions in living and nonliving things. In a human, swallowed food moves down the esophagus into the stomach, even if the human is upside down doing a handstand. Which force moves food through the esophagus into the stomach?.

Answer 1

The push force from contractions of the esophagus moves food through the esophagus.

A force is known as a push or pull that makes an object with a known mass accelerate in space or through a medium.

The action for the movement of food substances down the esophagus during the digestion process follows a free fall of gravity path.

movement of food substances down the esophagus follows a method where contraction occurs therefore resulting in a push force that takes the food into the stomach.
