Digestion In the Oral Cavity

Digestion In the Oral Cavity

Food enters the digestive tract during the oral cavity. The oral cavity contains several essential structures such as tongue, palate, teeth and launching of salivary glands. Know about cavity and its treatment  at . Four acts are performed from the dental cavity.

1. Choice of Food

First role of the nasal cavity would be to pick the food by flavor. A food with awful flavor is rejected. At the assortment of food smell and sight play an essential function. Social and emotional factors can also be involved in choosing a specific kind of food within the other.

2. Grinding of Food

When the food is within the mouth area, it's exposed to the grinding activity. Teeth, lips and tongue all participate in the bodily and speedy breakdown of food into smaller portions. Enzymes can quickly work on smaller meal particles.

3. Lubrication

The procedure for digestion and lubrication begins since the food has been broken down to smaller portions. Three pairs of these salivary glands secrete saliva that has three components:

1. Water and mucus

2. Sodium bicarbonate along with other additives

3. Enzyme–Amylase or ptyalin

Water and mucus

Water and mucus collectively make slimy liquid that mostly moistens and lubricates the food that is eaten. The meals could be chewed economically to permit the digestive juices to go into the food bulk.

Sodium bicarbonate

Sodium bicarbonate and other additives stabilize the pH of the meals even though they're slightly antiseptic. Fresh saliva is alkaline with a pH 8 but rapidly loses carbon dioxide also has to pH 6.


Amylase (Ptyalin) is a carbohydrate receptor that hydrolyzes glycogen and starch to maltose. Thus softened, partly digested food is currently arranged into little oral bumps called boluses.
