Abdominal sac

Stomach bag acts as container for food and contribute simultaneously to digestion by different chemical processes. Stomach starts just below the breathing muscle (the diaphragm or diaphragm) and below the rib verge slightly to the left. It is a J-shaped bag, which is an extension of the esophagus. On the transition between the esophagus and stomach, there is a thickening of the muscle that exists in the wall. This is called the upper stomach foot. This acts as closing muscle (sphincter) and must reg

There may be some. 1 liter in the stomach, and when it is filled, inflate it, while it is folded when it is empty. The bank's stomach wall, there are muscles that cause the stomach cankneadingstomach contents. When eaten, the stomach mixes the food together and get their food while mixed with stomach evening.

Inside of the stomach is lined with a mucous membrane, which produces abdominal evening. Abdominal consists Night of hydrochloric acid and a number of digestive enzymes to break down food. Abdominal Eve produced continuously, but production increases when you smell, see or hold food. Also produced a layer of protective slime, to prevent the stomach tonight damage the stomach itself. Stomach Night has a low pH, which ensures that the digestive enzymes are most active. Elsewhere than in the stomach, this l

In addition to mix food and gastric juice helps stomach Bank's movements in addition to push food further down in gut in small portions. The food is pushed forward only when it is well mixed with stomach evening. How much time elapses before a meal to proceed, depends on how much fat is in food. A high-fat meal worked for a long time in the stomach.

Between the stomach and gut is still a close muscle (sphincter) to be open so that food can pass. This is called the lower abdominal foot and is far more effective than the upper stomach foot. Some people may have problems that the lower abdominal foot becomes too narrow, so it is almost impossible for food to pass further down in the gut. This is called the narrowing of the lower abdominal foot (pyloric stenosis).


Gut is the first around. 25 cm long piece of small intestine and have received its name because the length equal to twelve fingers, placed side by side. The precursor C-shaped after the transition from the stomach. The diameter of the gut is 4-5 cm. Mucous membranes in the gut is finely folded to increase the surface. The larger the surface, the more of food nutrients can be absorbed through the mucous membranes. To further increase the surface bags mucous membranes also out in smalltattered, Which leads to mucous membranes is rather like velvet when you look closely at it. They called fringevilli. Each cell on the surface of the villi also serve as a kind of tattered, calledmikrovilli. These are so small that they can only be seen under microscope.

In gut-time leading export from the liver and gall bladder and pancreas. From liver and gall bladder bile is coming, as is necessary to be able to absorb fats. From the pancreas will be a large number of very effective digestive enzymes that are needed to be able to digest carbohydrates, fats and proteins. Gut is very important for the ability to digest food.

When the food comes from the stomach, is mixed with the acidic gastric juice. In order to mucous membranes in the gut is not affected by acid, some small glands in the mucous membranes, which produces alkaline mucus. Mucous membranes in the gut may well be affected by the acid, causing a stomach ulcer.
After gut continues leftovers continue through the rest of the small intestine.
