All activity of the person is inseparably linked with digestion as food provides it a possibility of physical and mental activity. One of the most important bodies on which the full-fledged comprehensibility of food depends is the pancreas.
Instruction
1. The pancreas – one of the largest internals, but is located it not under a stomach, and in a back part of an abdominal cavity. How it functions, also functions of many other vitals of the person depend. Its basic purpose – production of the enzymes participating in process of digestion and transforming the food coming to an organism to nutrients: proteins, fats, carbohydrates. It emits pancreatic juice which contains the enzymes splitting proteinaceous molecules: karboksipeptidaza And yes In, elastase, trypsin, ribonucleases, chymotrypsin and also those which split carbohydrates: amylase, lactose, maltose, invertaza and fats: lipase and holisteraza. But the most part of these enzymes to avoid self-digestion, in a pancreas is synthesized in a neutral, not active form. Their activation happens already at receipt in intestines, its catalyst is pancreatic juice which is emitted in a duodenum gleam.
2. Important function of a pancreas is not only production of necessary enzymes, but also regulation of their quantity depending on structure of food. If it is greasy food, in a pancreas the lipase and a holisteraza when proteins or carbohydrates prevail begins to be developed in bigger quantity, in pancreatic juice of a pancreas the amount of the enzymes destroying proteinaceous or carbohydrate connections, respectively increases. Such function allows to digest completely food regardless of composition of its ingredients, protecting digestive tract from overloads, and a pancreas – from self-destruction under the influence of the enzymes which remained "unclaimed".
3. But, as well as any gland – a pancreas participates in those processes which are regulated by an endocrine system in general. Its functions include also regulation of exchange processes by means of the produced hormones: glucagon and insulin. Getting to blood, these hormones participate in regulation of carbohydrate exchange. The lack of insulin can provoke developing of such disease as diabetes when the sugar which is contained in blood is not acquired in an organism and, so it lacks power sources for ensuring activity.
4. The correct functioning of a pancreas depends on a condition of a liver and a gall bladder which violations in work immediately affect also its state. Therefore important cares for health of the internals which all are closely connected with each other functionally.
