Describe how digestion is regulated
What will be an ideal response?
The enterogastrones gastrin, secretin, cholecystokinin, and gastric inhibitory peptide regulate digestion by stimulating or inhibiting the release of secretions from the stomach, small intestine, pancreas, and gallbladder. They also influence gastric motility, which controls the pace of digestion. The enteric nervous system is a network of nerves embedded in the wall of the GI tract. It functions both autonomously and in collaboration with the central nervous system and other nervous system branches to achieve GI functions. Two hormones, ghrelin and peptide YY, communicate with the brain to help you decide when to eat and when to stop eating.
