Duodenum

Duodenum The first part of the small intestine is the duodenum (deudenum), a length of twelve fingers adults. The process of digestion in the duodenum aided by the bile produced by the liver. Bile is green in color. In addition to bile, the digestive process of food in the gut 12 fingers aided by the pancreas gland. The pancreas gland produces three kinds of enzymes: a. enzyme amylase, the task: digesting carbohydrate / starch into sugars b. enzyme trypsin, task: to digest proteins into amino acids c. lipase enzyme, the task of digesting fats into fatty acids in the intestine 12 So finger foods are digested more because there are foods that have not been destroyed in the stomach. After experiencing the destruction of the intestine 12 finger food is a liquid slurry that is very smooth. Next by peristalsis into the small intestine. Sources: digestive system Kirei's blog a. Twelve Fingers intestine Bowel is called duodenum because of the length of about 12 fingers lined up parallel. Inside the walls of the duodenum there is a channel along the estuary of the gallbladder contains bile produced by the liver. Useful for emulsikan to fat. Greenish bile and bitter taste. The pancreas is located below the stomach and pancreas produce sap. Lymph containing pancreatic enzymes amylase, trypsinogen, and lipase. Amylase convert starch into sugar. Trypsinogen is an enzyme that is not yet active but can be activated first by the enzyme enterokinase generated by the small intestine. Enzyme enterokinase convert trypsinogen into active tirpsin. Trypsin convert proteins into peptides and amino acids. Lipase convert fat into fatty acids and glycerol. These substances are easily absorbed products of digestion by the intestinal wall through the process of diffusion and osmosis. Substances that have not decomposed can enter the intestinal cell membrane through active transport. Sources: lovianettesherry

Gastric inhibitory peptide (GIP) or Enterogastrone, produced by usus12 finger and inhibit labor gastric glands and muscles that protect the intestine 12 fingers from damaging stomach acid as well as controlling the rate of gastric emptying.

Atrial Natiuretic Factor, helping expenditure balance of salt and water so it does not directly regulate homeostasis of the kidney and cardiovascular system. This hormone works with Aldosterone antagonists.

Secretin, produced by the small intestine that is triggered by the presence of acid in the intestine 12 fingers. This hormone stimulates the pancreas to secrete digestive enzymes including bicarbonate ions. Bicarbonate ions buffer the acidity is pureed food (chyme) entering the small intestine from the stomach. This hormone also stimulates the liver and gall bladder to secrete bile.

The surface of the ileum wall full of flakes or intestinal villi. Intestinal tuft surface causes the surface of the ileum into broad absorption of nutrients so that the process can run well. Absorption of nutrients by the small intestine is called absorption. Foods that are experiencing chemical digestion of carbohydrates, proteins, and fats. The end result of digestion of carbohydrates is glucose, proteins into amino acids, and fats into fatty acids and glycerol. Vitamins and minerals are not experiencing the process of digestion. Glucose, amino acids, vitamins, and intestines. Supplied with food nutrients through blood vessels to precautionary. Glucose is stored partly in the form of glycogen in the liver that is not soluble in water. Some other nutrients in the cells circulate throughout the body via blood vessels. Fatty acids and glycerol are transported through the vessels kil because molecular size is large enough. Kil vessels are lymph vessels or lymph vessels in the intestine. The next vessel will kil kil join other vessels and eventually lead to the minerals into the blood vessel capillaries contained in tuft lymph vessels under the collarbone

Duodenum, Pars superior, pars descendens, Pars horizontalis


Duodenum



Duodenum or duodenum is a part of the small intestine that is located after the stomach and connecting it to the empty intestine (jejunum). Bowel twelve finger is the shortest part of the small intestine, starting from the bulbo duodenale and ends at Treitz ligament. Duodenum is a retroperitoneal organ, which is not covered entirely by the peritoneal membrane. intestinal pH twelve fingers normal range in nine degrees.Duodenum is responsible for distributing food to the small intestine. Histologically, there Brunner glands that produce mucus. Twelve of the intestinal wall is composed of fingers layers of very thin cells that form the mucosal muscles.
Parts Duodenum, Pars superior first part, which starts from suoerior Pars end of the pylorus pylorus is the lower part, the area associated with the 12 finger intestine (duodenum). Then the channel will be pulled into the right lateral. This section has a length of 5 cm. The second part of pars descendens, descendens pars continue the first part. This section bebentuk straight down the channel, In this section there is the estuary of the pancreatic duct and bile duct communis which coalesce into hepatopankreatika duct. In addition, a bulge terdpaat also called duodeni papilla.Pars horizontalis third section, Pars horizontalis shaped horizontal channel, through the inferior vena cava, aorta, and spine. Pars ascendens last section, funnel-shaped pars ascendens ascending and ends at the beginning of the empty intestine (jejunum).


Brunner's glands are submucosal glands in the duodenum. Its main function is to produce alkaline secretion containing bicarbonate for :
  1. Protect the duodenum from acid substances from the judge (a collection of food from the previous digestion).
  2. as a lubricant of the intestinal wall.
  3. provide alkaline conditions for intestinal enzymes to be active. The enzyme functions to start the absorption.Enzymes are biomolecules that serve as a catalyst (substance that speeds up the reaction without reacting) in a chemical reaction, the enzyme works by attaching molecules to the surface of substances that react and thus accelerate the reaction process, enzyme Work influenced by several factors, especially is the substrate, temperature, acidity, cofactors and inhibitors. Each enzyme requires the temperature and pH (acidity level) optimum different because enzymes are proteins, which can change shape if the temperature and acidity changes.
