What is the role of the duodenum?

In the gastrointestinal system, the small intestine consists of two separate parts - duodenum and ileum. The duodenum is shorter of two parts and is a place where most of the digestion occurs. The ileum is significantly longer and largely concerns the absorption of nutrients and molecules released during digestion. The duodenum is connected to the stomach with a pyloric sphincter. It works as a way of controlling the flow of material from the stomach to the small intestine. Chyme - partially cleaved food - can only pass in one direction through the sphincter, from the stomach to the small intestine. The food is divided into smaller pieces and creates a creamy mixture called caught. Within three to four hours after eating food, we gradually release to the duodenum. This allows for a small amount of food at a time, ensuring thorough digestion and continuous food supply that will be absorbed between meals.

digesce occurs in the duodenuda addsIt is various digestive juices. The three sources of digestive juices that perform this process are the liver, the pancreas and the wall of the small intestine. The walls of the small intestine are folded and characterized by villi-with a fingers similar to projections. Killi contains smooth muscle cells that allow them to download and relax so that the food is further mixed with digestive juices, and also move through the small intestine.

Three digestive juices that are released into the duodenum are bile, pancreatic juice and intestinal juice. The bile is produced by the liver. It contains mineral salts and bile salts that help regulate pH caver also break fats and oils into smaller molecules for easier digestion. There are no digestive enzymes in the bile.

and also containing mineral salts, pancreatic juice contains several different enzymes. Each of these enzymes works on a different type of food molecule to divide into its components. When food moves over the twelve enzymes, it is thoroughly mixed with these enzymes so that toDyž reaches the ileum, is divided into small molecules, which can then be absorbed into the body.

intestinal digestive juices contain mucus, mineral salts and enzymes. Mucus and mineral salts are produced by Brunner's glands and enzymes are produced on the tip of Villi in the duodenum. Mucus and mineral salts help lubricate duodenum and regulate pH, while enzymes perform digestion of breaking proteins, lipids and carbohydrates.
