Q. When does digestion begin?
Pop a grape, a chocolate, or a shrimp into your mouth. Immediately, digestion begins. In the mouth itself, the tongue and teeth help to get the process started by chewing and chopping the food so it’s small enough to be swallowed. This activity, aided by the chemical composition of your diet, is catalyzed by salivary glands, which secrete saliva, releasing an enzyme that starts changing some starches into simple sugars and softening the food for swallowing. The saliva also allows the taste buds of the tongue to sense the flavors of your foods.
Swallowing is a complicated, coordinated act that you begin by using your tongue to push food back into your throat or pharynx. This voluntary action sets off an involuntary chain of events that transports the food from the throat into the esophagus and down into the stomach, a journey that typically takes eight seconds.
The time it takes for food to pass through all sections of the digestive tract can be anywhere from 9 hours to over 3 days
