Question

explain digestion in stomach​

Answer 1

Answer :-

The digestion of food inside the stomach, is as follows :-

• The swallowed food material enters the stomach through the "Oesophagus" (Food pipe).

• The stomach secretes "Gastric Juice".

• The pH of the "Gastric juice" lies between the range of 1 to 3.5

• The stomach is the chief site of digestion of "Proteins".

• Food mixed with gastric juice inside the stomach, is known as "Chyme".

• The columnar epithelium of stomach forms many gastric pits along with gastric glands.

• Gastric glands are located on the Mucosa of the stomach.

• The Peptic or Zymogen cells secrete digestive proenzymes namely "Pepsinogen" and "Prorenin".

• The oblique muscles of the stomach help in the churning of food inside the stomach.

• The "Oxyntic cells" of the stomach secrete Hydrochloric Acid (HCL).

• The Hydrochloric acid helps in the activation of "Pepsinogen".

• The Hydrochloric acid helps in killing the harmful microbes present inside the swallowed food material.

• After the completion of digestion inside the stomach, the food heads towards the small intestine for further simplification, through the "Duodenum".
