Why does food move down the esophagus and through the stomach automatically even when a person is resting or sleeping?
  1. The walls of the digestive organs contain involuntary smooth muscles
  2. Gravity is the only force pushing the food down
  3. Skeletal muscles continuously pull food downwards
  4. Joints inside the stomach propel the food

Solution

Movement of food in the digestive tract occurs due to peristalsis, driven by involuntary smooth muscles in the organ walls.
