how does the endocrine interact with the digestive system?
Answer:
The digestive system is controlled by the synchronized action of
the brain and the endocrine system by releasing specific hormones
required for the digestion of food.
During the gastric phase, the brain induces the endocrine system,
and the G cells of the stomach release the gastrin hormone which
helps in protein digestion by producing acids. The action of
gastrin is controlled by another hormone called somatostatin which
controls the production of gastrin in an empty stomach.
The coupled action of endocrine hormones secretin and
cholecystokinin induces the production of pancreatic juices and
bile in the duodenum. This alkaline fluid neutralizes the acidic
content of the stomach.
During high lipid diets, the small intestine secretes gastric
inhibitory peptide to reduces the peristaltic movements of the
intestine. The lower the peristaltic movement, the higher the time
for lipid breakdown.
