SuaraJogja.id – Here is an explanation of Oral cavity function. This cavity is the beginning of Digestive system People to then travel 10 meters Colon.

The digestive tract, as described in the book Digestive System by Khamim, S.Pd. cited from the mouth, throat, esophagus, stomach, small intestine, large intestine and anus.

The digestive system is also supported by three organs that are located outside of the digestive tract. These organs are the pancreas, liver, and gallbladder.

In this article, we will focus on discussing the function of the oral cavity, what its components are, and how they work. Check out the following reviews:

Early digestive system

The mouth is an open cavity into which food and water enter. The mouth is on the head and is generally the first part of the digestive system.

The inside of the mouth is lined with a mucous membrane. The ducts of the salivary glands, located on the cheeks, under the tongue, and under the jaw, drain their contents into the mouth. At the bottom of the mouth there is a tongue that is used to taste and mix food.

The taste is perceived through the sensory organs on the surface of the tongue. Then the smell is perceived through the olfactory nerve in the nose. The taste is relatively simple and consists of sweet, sour, salty and bitter.

It is true that smell is more complicated because it is made up of different types of smells. Behind and under the mouth is the pharynx or pharynx.

Function of teeth in the oral cavity

In the oral cavity there are teeth made up of canines, posterior teeth, central teeth, premolars and molars.

The front teeth, also called incisors, are used to chop up food. Then the molars or molars are used to chew food to become smaller parts that are easier to digest.

Food, broken down into small pieces, becomes enveloped in saliva from the salivary glands with digestive enzymes and begins to digest it.

The function of saliva in the oral cavity

When you eat, the flow of saliva washes away bacteria that can cause tooth decay and other diseases. Saliva also contains antibodies and enzymes like lysozyme that break down proteins and attack bacteria directly.

This food travels down the throat. In the pharynx, there are spiglottic valves on the right and left sides of the pharynx. The function of the spiglottis is to keep food from entering the trachea and lungs.

No less important than the spiglottis, the roof of the mouth or the soft palate, is raised so that no food gets into the nose.

System according to the oral cavity

After passing through the oral cavity and throat, food enters the esophagus, stomach, small intestine, large intestine, and anus.

Food is sorted, which is needed by the body and which is not. This process takes place in the small intestine when food meets enzymes and other substances, such as bile from the cells of the intestine, bile, liver and pancreas.

These substances build up carbohydrates, fats and proteins that are processed into compounds that are absorbed by the body and used as energy. The resorption process takes place in the small intestine.

In the meantime, food that is not needed is directed into the large intestine and processed into feces and excreted from the anus. The anus itself is actually a part of the colon, like the rectum, where feces collects before excreting through the anus.

Such is the discussion of the function of the oral cavity that emerges from the book Digestive System, pages 1-4, by Khamim, S.Pd. Hopefully it can expand knowledge about the digestive system, especially the mouth.
