Question

How is thorough chewing of food helpful in digestion?

Answer 1

Hint:The digestive tract inside our body starts from the mouth; where most of the foods get break-down through chewing to the esophagus and from stomach to the intestine where it gets absorbed and the digestion process gets completed.

Complete answer:
To answer this question, we have to know details about the digestive process. The very first organ of the digestive tract involves the mouth through which we intake our food and chew it for the break-down of food. The stomach has three basic functions; storage of food, breakdown of food into simple compounds, and mixing of food with the enzymes used for digestion. The stomach consists of a mucosa layer that is a specialized cell and glands that form the hydrochloric acid and enzymes involved in the digestion process. The mucosa releases mucus that protects the inner lining of the stomach from the hydrochloric acid formed inside the stomach. Another cell that is produced inside the mucosa is the gastrin hormone that releases the enzyme and the acid from the mucosa and helps in muscle contact of the stomach. The food gets mixed and crushed and forms chyme and the pyloric sphincter relaxes when the chyme formation gets complete. The chyme then moves inside the duodenum that helps in the absorption of food that we eat.
Now, to complete the proper digestion process we should chew our food thoroughly. This small task of chewing of food tends to help in splitting of bulk food particles into smaller particles. This decreases the pressure on the oesophagus and thus results in proper metabolism of our food inside the stomach. We also release a lot of saliva when we chewing the food and the saliva contain the digestive enzymes that directly help in the digestion process,

Note:The hydrochloric acid found inside the stomach is involved in the production of some other digestive enzymes and in break-down of complex substances into simple substances. And from the stomach the chymes moves to the intestinal part for the absorption of required products and excretion of the unwanted products.
