the pancreas secretes digestive enzymes into the duodenum.
where does the pancreas secrete digestive enzymes into?
the duodenum
the pylorus, the lowest section of the stomach which attaches to the duodenum via the pyloric canal, contains countless glands which secrete digestive enzymes including gastrin. after an hour or two, a thick semi-liquid called chyme is produced. when the pyloric sphincter, or valve opens, chyme enters the duodenum where it mixes further with digestive enzymes from the pancreas, and then passes through the small intestine, where digestion continues. when the chyme is fully digested, it is absorbed into the blood. 95% of absorption of nutrients occurs in the small intestine. water and minerals are reabsorbed back into the blood in the colon of the large intestine, where the environment is slightly acidic. some vitamins, such as biotin and vitamin k produced by bacteria in the gut flora of the colon are also absorbed.
human digestive system
microbes simply secrete digestive enzymes into their surroundings, while animals only secrete these enzymes from specialized cells in their guts, including the stomach and pancreas, and salivary glands. the amino acids or sugars released by these extracellular enzymes are then pumped into cells by active transport proteins.
