Digestive Enzymes â List of Glands, Organs and Volume Digestive Enzyme Glands The alimentary tract, also known as the gastrointestinal tract or gut, is structured in a manner that allows for optimal digestion and absorption of foods. Digestive enzymes are secreted from alimentary glands that lie in the lining of the gastrointestinal tract or may travel to the gut from external organs and glands like the liver, salivary glands and pancreas.

Accessory Organs of Digestion : The salivary glands are ductile glands that are present in the mouth. Salivary glands consist of two types of secretory cells. First, would be the serous cells that secrete the digestive enzyme amylase and the second would be the mucus cells which secrete the thick slimy fluid mucus.

Pancreas The pancreas is also a digestive organ, secreting pancreatic juice containing digestive enzymes that assist digestion and absorption of nutrients in the small intestine. These enzymes help to further break down the carbohydrates, proteins, and lipids in the chyme.he pancreas is a secretory structure with a internal hormonal role (endocrine) and an external digestive role (exocrine) . It has two main ducts, the main pancreatic duct, and the accessory pancreatic duct. These drain enzymes through the ampulla of Vater into the duodenum.

Anatomy and Physiology: Digestive System In most vertebrates, the stomach is located between the esophagus and the small intestine. It secretes protein-digesting enzymes called proteases and gastric acid to aid in food digestion, through smooth muscular contractions before sending partially digested food (chyme) to the small intestines.

Exocrine Secretions of the Pancreas Three major groups of enzymes are critical to efficient digestion: 1. Proteases. Digestion of proteins is initiated by pepsin in the stomach, but the bulk of protein digestion is due to the pancreatic proteases. Several proteases are synthesized in the pancreas and secreted into the lumen of the small intestine. The two major pancreatic proteases are trypsin and chymotrypsin, which are synthesized and packaged into secretory vesicles as an the inactive proenzymes trypsinogen and chymotrypsinogen.

Control of Pancreatic Exocrine Secretion 1 As chyme floods into the small intestine, cholecystokinin is released into blood and binds to receptors on pancreatic acinar cells, ordering them to secrete large quantities of digestive enzymes.  Secretin: This hormone is also a product of endocrinocytes located in the epithelium of the proximal small intestine. Secretin is secreted (!) in response to acid in the duodenum, which of course occurs when acid-laden chyme from the stomach flows through the pylorus.

Anatomy of the Digestive System Mouth and Salivary Glands. Digestion begins in the mouth, where chemical and mechanical digestion occurs. Saliva or spit, produced by the salivary glands (located under the tongue and near the lower jaw), is released into the mouth.Saliva begins to break down the food, moistening it and making it easier to swallow.A digestive enzyme (amylase) in the saliva begins to break down the carbohydrates (starches and sugars).One of the most important functions of the mouth is chewing. Chewing allows food to be mashed into a soft mass that is easier to swallow and digest later.aliva begins to break down the food, moistening it and making it easier to swallow. A digestive enzyme (amylase) in the saliva begins to break down the carbohydrates (starches and sugars). One of the most important functions of the mouth is chewing.

Biology Ch 5-16 Hormones can play a role in the release of digestive secretions. For example, secretin is a hormone produced in the walls of the small intestine that stimulates the liver to produce bile and the pancreas to release bicarbonate, which neutralizes the acidity of the chyme.

What Is the Pancreas? - Function, Enzymes & Role in Digestion The pancreas is a vital digestive organ because it produces a variety of enzymes that break down all of the major food groups. These enzymes are secreted into the duodenum along with a high concentration of bicarbonate. Bicarbonate makes the pancreatic secretions alkaline in nature.hree enzymes found in pancreatic juice, called trypsin, chymotrypsin and carboxypeptidase, are the pancreatic enzymes that complete the digestion of proteins. Because proteins are held together by peptide bonds, these enzymes work by breaking peptide bonds.
