How does the stomach mechanically digest the food?

Answer 1

Once in the stomach, more chemical and mechanical digestion occurs. The crushing and breaking action of the stomachs contractions with HCl help not only break down food, but also lend a hand in converting pepsinogen to the enzyme pepsin. This enzyme in the stomach takes the roll of the chemical digester, and breaks certain peptide bonds, thereby breaking up proteins in the stomach. Partly digested food from the stomach now travels to the small intestine, through the pyloric sphincter, and is know as chyme.

Answer 2

Some foods are immediately absorbed into the bloodstream (like simple sugars). Other foods need to be broken down into their biologically active forms. There are proteins in your saliva and stomach called enzymes which carry out this process. You need different enzymes for to breakdown carbohydrates, proteins, and fat. A single enzyme can be used repeatedly; they grab onto a food molecule, break it apart, and then it's ready to break another down. Some enzymes require a certain pH to be active, which is why the stomach is really acidic.

Answer 3

food undergoes two types of digestion in the stomach.One is mechanical digestion which is the the churning of food or peristalsis.Second is chemical digestion which involves enzymes (protease) breaking down substances in simpler forms.the food after digestion in the stomach becomes a thick liquid which is then sent to the small intestine.

Answer 4

No. Mechanical digestion in the stomach is accomplished by the three muscular layers that churn the chyme (food plus saliva and gastric juices) in the stomach. Pepsin is a digestive juice produced by the combining of HCl acid and pepsinogen. It is involved in chemical digestion. Bile is not involved in the digestive processes in the stomach. It is produced by the liver, temporarily stored in the gallbladder, and secreted into the duodenum, the first part of the small intestine. It is responsible for the emulsification of fats and plays no role in mechanical digestion at all.

Answer 5

The contractions in the throat push down the food into the stomach and the enzymes break down the food into waste, nutrients. Which provide our body with energy that we need to survive.

Answer 6

Mechanical: stomach's motions serve to break down the food physically into slightly smaller sizes

Chemical: Stomach acid

Answer 7

the acids in your stomack burn the food in to a solid and if you drink something like water, juice,etc it messes up the acids and it dont work right :)
