The fluid containing digestive enzymes secreted by the pancreas in response to food in the duodenum.
The alkaline digestive juice produced by the pancreas and secreted into the duodenum.
A digestive juice, formed of enzymes produced by the pancreas, which digests fats and carbohydrates.
Fluid secretion of the pancreas, containing water, salts, and enzymes, including trypsin and chymotrypsin; it is essential for the breakdown of starches, proteins, and fats.
The digestive juice secreted by the pancreas. Its production is stimulated by hormones secreted by the duodenum, which in turn is stimulated by contact with food from the stomach. If the duodenum produces the hormone secretin the pancreatic juice contains a large amount of sodium bicarbonate, which neutralizes the acidity of the stomach contents. Another hormone causes the production of a juice rich in digestive enzymes, including trypsinogen and chymotrypsinogen (which are converted to trypsin and chymotrypsin in the duodenum), amylase, lipase, and maltase.
A clear, viscid, alkaline fluid (pH 8.4 to 8.9); its secretion is stimulated by two hormones, secretin and cholecystokinin, produced by the duodenal mucosa. Pancreatic juice flows through the main pancreatic duct to the common bile duct to the duodenum, its site of action; 500 to 1200 ml is secreted every 24 hr. It contains sodium bicarbonate and the enzymes trypsinogen, chymotrypsinogen, amylase, and lipase. Sodium bicarbonate neutralizes the acidity of the chyme entering the duodenum from the stomach and prevents irritation of the duodenal mucosa. Trypsinogen is converted to active trypsin by intestinal enteropeptidase (enterokinase), and trypsin in turn converts chymotrypsinogen to active chymotrypsin. Both trypsin and chymotrypsin continue protein digestion, forming peptides. Amylase hydrolyzes starch to maltose, and lipase digests emulsified fats to fatty acids and glycerol.
A fluid produced by the pancreas that comprises three digestive enzymes: amylase for breaking down carbohydrates, lipase for fats, and trypsin for proteins.
