Digestion in Buccal Cavity



Carhohydrate digestion in the oral cavity

  • The salivary glands in the oral cavity secrete saliva, which helps to moisten the food.
  • The food is then chewed while the salivary glands also release the enzyme salivary amylase, which begins the process of breaking down the starch into maltose, isomaltose and alpha dextrins.


Mouth (Buccal cavity)

  • The buccal cavity is the first cavity of the alimentary canal which includes teeth, tongue, and palate (Palate is the roof of the mouth. It separates the mouth and the nose.).
  • The buccal cavity helps to take the food inside by the process of ingestion (ingestion is the process of taking food into the body).



Teeth break the food into smaller particles which help in proper digestion.
Saliva mixes with the food particles to moisten it. Digestion of carbohydrates starts from the mouth.



The tongue is a muscular organ.
It is attached to the back of the buccal cavity. In the front, it can move freely in all directions.
The function of the tongue is to push the food forward and help us to swallow it. 
It is also used to taste food.
Food can be tasted with the help of taste buds present on the tongue. 



The role of the soft palate is to block the nose when the food is being swallowed.
They guide the food particles into the esophagus. This prevents the food to move to the respiratory tract.
