Answer 2

Hello ,

" It is involved in the second phase of digestion, following mastication (chewing). The word stomach is derived from the Latin stomachus,[3] which derives from the Greek word stomachos (στόμαχος). The words gastro- and gastric (meaning related to the stomach) are both derived from the Greek word gaster (γαστήρ). The stomach churns food before it moves on to the rest of the body."

It also does the final breaking down of food with lots of chemicals and acids. (:

Answer 3

The stomach has two main jobs; to chemically and physically break down food. There are three separate rings of muscle in the stomach that turn in different directions to break down food physically. There is also a number of chemicals, including amylase, hydrochloric acid, pepsin, and lipase all break down different molecules. Pepsin breaks down proteins, lipase breaks down fat droplets, and hydrochloric acid breaks down a multitude of polysaccharides into disaccharides.

Answer 4

Role in DigestionBolus (masticated food) enters the stomach through the esophagus via the esophageal sphincter. The stomach releases proteases (protein-digesting enzymes such as pepsin) and hydrochloric acid, which kills or inhibits bacteria and provides the acidic pH for the proteases to work. Food is churned by the stomach through muscular contractions of the wall - reducing the volume of the fundus, before looping around the fundus[3] and the body of stomach as the boluses are converted into chyme (partially-digested food). Chyme slowly passes through the pyloric sphincter and into the duodenum, where the extraction of nutrients begins. Depending on the quantity and contents of the meal, the stomach will digest the food into chyme anywhere between 40 minutes and a few hours.

Answer 5

The stomach's role is to mechanically break foods down into smaller pieces for digestion in the intestines, as well as to start breaking down the amino acid bonds in proteins.
