GENERAL HISTOLOGY

Detailed explanation-1: -Tongue is a muscular organ present in the buccal cavity. It helps in mixing the food with saliva during chewing and helps in swallowing it.

Detailed explanation-2: -When we chew, the tongue and the cheeks work together to constantly move the food between the teeth so that it can be chewed. The tongue presses the crushed food against the palate and moves this bolus, which is then ready to be swallowed, to the throat.

With the help of the tongue, the resulting bolus is moved into the esophagus by swallowing. The extensive chemical process of digestion begins in the mouth.
