Trypsinogen, chymotrypsinogen, pancreatic lipase and amylase in pancreas.
The accessory organs of digestion include the salivary glands, pancreas, liver, and gallbladder The pancreas makes digestive jucies called enzymes which help to digest food fu … rther. The gall-bladder stores bile (which is made in the liver), the bile helps to digest fatty acids. The liver secretes a substance called bile into the gallbladder, where it is stored for eventual use in digestion. Bile is a fluid mixture composed of bile pigment and bile salt. The organs produce digestive chemicals (enzymes and acids) that break down the nutrients into simpler forms so that absorption through the intestinal wall and into the blood stream can occur. Mechanical and Chemical Digestion. There are two kinds of digestion: mechanical and chemical.  The organ that produces and secretes enzymes that are essential for  proper digestion is the pancreas. The enzymes that the pancreas  produces and secretes are trypsinogen, … , chymotrypsinogen,  pancreatic lipase and amylase. 2 people found this useful. I know 3 of them, which is stomach, small intestine, and large intestine. What is an “Accessory” Organ? The digestive system has several accessory organs that aid in the process of digestion. An accessory organ is one that helps with the breakdown of food without the food ever traveling through them – they are not part of the digestive tract or tube. The accessory organs of digestion include: Salivary Glands Liver Gall Bladder Pancreas The Salivary Glands The salivary glands are small organs found both above and below the oral cavity. The secrete a watery substance, called saliva, that contains both amylase and mucus. In addition to the alimentary canal, vertebrate digestive systems include the following accessory organs: The liver secretes a substance called bile into the gallbladder, wh … ere it is stored for eventual use in digestion. I know 3 of them, which is stomach, small intestine, and large intestine. Accessory digestive organs aid digestion physically and produce secretions that break down foodstuff in the GI tract; the organs involved are the teeth, tongue, gallbladder, salivary glands, liver, and pancreas. Digestive Processes. Ingestion is the simple act of putting food into the mouth.  Secretion. The stomach produces and secretes several important substances to control the digestion of food. Each of these substances is produced by exocrine or endocrine cells found in the mucosa. 1  The main exocrine product of the stomach is gastric juice – a mixture of mucus, hydrochloric acid, and digestive enzymes. Digestion. Digestion in the stomach can be divided into 2 classes: mechanical digestion and chemical digestion. Mechanical digestion is the physical division of a mass of food into smaller masses while chemical digestion is the chemical conversion of larger molecules into smaller molecules. The mixture of mucus, hydrochloric acid, and pepsin is known as gastric juice. Gastric juice mixes with food to produce chyme, which the stomach releases into the duodenum for further digestion. The gallbladder stores and secretes bile into the duodenum to aid in the digestion of chyme. A mixture of water, bile salts, cholesterol, and bilirubin, bile emulsifies large masses of fats into smaller masses. The pancreas stores and secretes pancreatic juice into the duodenum to complete the chemical digestion of food that began in the mouth and stomach. Pancreatic juice contains a mixture of enzymes including amylases, proteases, lipases, and nucleases. Pancreas and Fat Digestion. The pancreas is a leaf-shaped organ that lies below the stomach. It secretes juices containing enzymes that are capable of digesting all major types of food -- carbohydrates, fats and proteins. The pancreas is the first organ to begin digesting fats. The deep spaces between the villi are called crypts, which secrete mucus, bicarbonate and water. In addition to these secretions, the cells of the small intestine also produce hormones, like secretin and cholecystokinin, which stimulate the other organs to release their digestive juices.
