Answer:
Digestion in human:
In chemical digestion, enzymes break down food into the small molecules the body can use.
In the human digestive system, food enters the mouth and mechanical digestion of the food starts by the action of mastication (chewing), a form of mechanical digestion, and the wetting contact of saliva.
Peristalsis movement:
Peristalsis is a series of wave-like muscle contractions that moves food to different processing stations in the digestive tract. .
The strong wave-like motions of the smooth muscle in the esophagus carry the food to the stomach, where it is churned into a liquid mixture called chyme.
