What is the process of the stomach?

Answer 1

the stomach is a vital part of the digestive stomach

it is a bag like structure it h has the upper part known as the cardiac stomach guarded by the cardiac spincter and the middle part known as the fundic stomach and thelast known as the pyloric stomach guarded by the pyloric spincter.

the wals of the stomach contain mucus cells secreting mucous

the oxyntic cells secreting HCl and the gastric galnds secreting gastric juice

Answer 2

The digestive glands that act first are in the mouth-the salivary glands. Saliva produced by these glands contains an enzyme that begins to digest the starch from food into smaller molecules. An enzyme is a substance that speeds up chemical reactions in the body.

The next set of digestive glands is in the stomach lining. They produce stomach acid and an enzyme that digests protein. A thick mucus layer coats the mucosa and helps keep the acidic digestive juice from dissolving the tissue of the stomach itself. In most people, the stomach mucosa is able to resist the juice, although food and other tissues of the body cannot.

After the stomach empties the food and juice mixture into the small intestine, the juices of two other digestive organs mix with the food. One of these organs, the pancreas, produces a juice that contains a wide array of enzymes to break down the carbohydrate, fat, and protein in food. Other enzymes that are active in the process come from glands in the wall of the intestine.

The second organ, the liver, produces yet another digestive juice-bile. Bile is stored between meals in the gallbladder. At mealtime, it is squeezed out of the gallbladder, through the bile ducts, and into the intestine to mix with the fat in food. The bile acids dissolve fat into the watery contents of the intestine, much like detergents that dissolve grease from a frying pan. After fat is dissolved, it is digested by enzymes from the pancreas and the lining of the intestine.

Answer 3

Short answer: the extra muscular layer helps for more segmentation, movement, and grinding of food.

Long answer: il make a little list of the adaptations of the stomach to its function.

-The stomach is folded up to begin with then as food passes into it it unfolds allowing more food to be taken in.

-the stomach contains small pits around the lining (gastric pits). These contain cells that secrete hydrochloric acid and peptinogen which, in the presence of the acid turns to peptin. This is an enzyme that starts to break down proteins. (its an endopeptidase).

-there are muscles at the entrance and exit of the stomach that allow food to pass in.

-food is mashed up to a substance called chyme by a process called peristalsis which basically means contracting the stomachs muscles to turn the food into a acidic paste. This helps it to be broken down and absorbed in the gut (small and large intestine).

-not sure if this is 100% accurate but i think the stomach contains pressure detecting receptors that trigger the release of the hcl and peptinogen. These are activated when the food passes into the stomach and moves across them.
