Functions of Stomach in Digestive System

Following are the functions of stomach:

• The major function of the stomach is to store and digest the food and liquids we intake.
• It produces hydrochloric acid which helps in digesting food and killing foreign substances like bacteria.
• The stomach helps in absorption of minerals like phosphate, calcium, and iron.
• The stomach muscles contract at regular intervals to churn the food ingested and makes the digestion process for other parts easier.
• Stomach releases enzymes like pepsin (secreted by chief cells as an inactive zymogen called pepsinogen, which is converted into pepsin by the action of HCl), gastric amylase, and gastric lipase, which helps in the absorption of proteins, simple sugars, and lipids (lipid digestions starts from here).

Diagram of Stomach with labels gives us an understanding of the stomach’s anatomy as well as its physiology. The stomach is a hollow organ that is part of the gastrointestinal system, present in the upper left part of the abdomen. The diagram of stomach in human body shows its functions as the formation of chyme, synthesis of proteins necessary for vitamin absorption (e.g. pepsin), microbial defences, and propagation of the peristaltic reflex. The diagram of stomach class 10 is an important diagram for the board examinations, hence studying it properly becomes crucial.
