The mouth
is the beginning of the digestive tract. In fact, digestion starts here as soon as you take the first bite of a meal. Chewing breaks the food into pieces that are more easily digested, while saliva mixes with food to begin the process of breaking it down into a form your body can absorb and use.

to inactivate swallowed microorganisms, thereby inhibiting infectious agents from reaching the intestine
.

ingestion, propulsion, mechanical breakdown, chemical digestion, absorption, and elimination
. First, food is ingested, chewed, and swallowed. Next, muscular contractions propel it through the alimentary canal and physically break it down into tiny particles.
What is the mechanical digestion of stomach?
After passage through the esophagus, the bolus will enter the stomach and undergo mechanical and chemical digestion. Mechanical digestion in the stomach occurs via
peristaltic contractions of the smooth muscle from the fundus towards the contracted pylorus
, termed propulsion.
