What is the function of a human tongue?

Answer:
The tongue rolls the food into balls or boli (singular: 'bolus') and pushes them to the back of the buccal (mouth) cavity for swallowing.

The tongue is not considered as part of the respiratory system, mostly on account of it not assisting in breathing. It is part of the gastrointestinal (digestive) system. The tongue helps you to swallow, then peristaltic action propels food, now called a bolus, down the esophagus.


Tasting and Processing the Food: Your tongue works along with our teeth, lips and mouth to taste, chew, and swallow food. Your teeth help your tongue grind food as the tongue mixes the food around your mouth. Without your teeth, lips, and the roof of your mouth, your tongue wouldn't be able to form sounds to make words. Saliva is needed for the proper functioning of the tongue. A dry tongue can't taste a thing so saliva helps the tongue and our sense of taste by keeping it wet. Saliva moistens food and helps to break it down, which in turn makes it easier for the tongue to push the food to the back of the mouth for swallowing.
