HUMAN DIGESTIVE SYSTEM

ORAL CAVITY OF HUMAN BODY

Process of digestion in oral cavity

Process of digestion in oral cavity

ORAL CAVITY works in some steps the most obvious are

*1* Selection of food

*2*Grinding or Mastication

*3*Lubrication

*4* Digestion

SELECTION OF FOOD IN THE ORAL CAVITY

When food enter in to the mouth it touches with tongue , teeth, cheeks.Then it tasted felt and Smelled.It taste ,smell or feel is bad or there is any hard object or dirt in it then it being rejected by human mouth.

Tongue is the most important part of oral cavity , it is a sensory and muscular organ which select food with the help of taste buds which are extended on the outer side of the tongue.

GRINDING AND MASTICATION OF FOOD IN THE ORAL CAVITY

After the process of selection of the food in the oral cavity the next step is to ground the food in to the smaller pieces with the teeth and molars in the oral cavity. This step is very useful and helpful in the process of digestion of food . it has many benefits which are these(a)The food in the form of small pieces is helpful for enzymes to digest the food.(b)The canal after the oral cavity (ESOPHAGUS) can pass the food in the form of small pieces easily.

LUBRICATION AND DIGESTION OF FOOD IN THE ORAL CAVITY

There are there types of glands in the oral cavity which secretes saliva.These are listed below.

*Sub lingual glands* These are extended below the tongue

*SUB MAXILLARY GLANDS* These glands extended behind the JAWS

*PAROTID GLANDS* These glands existed in the front of ears

All these glans secreted saliva which lubricate the food which is in the mouth . This Saliva contain digesting enzymes like SODIUM BICARBONATE ,WATER ,AMYLASE AND MUCUS .

The work of these enzymes is that the water and and the mucus get mixed with each other and give a good amount of moist to the food which is very helpful to tore the food piece in the small pieces and give smoothness to the food and help out the food to pass through the canal after the oral cavity with ease.

The work of sodium bicarbonate is to the balancing the PH level of the food which enters in the oral cavity and it slightly anti biotic also. AMYLASE is the enzyme which is good in the process of digestion of the starch in the food.
