In addition to producing digestive enzymes, the pancreas produces hormones that regulate
a. blood glucose levels.
b. HCl production by the stomach.
c. blood calcium levels.
d. bicarbonate secretion into the small intestine.
e. pH of the blood.
A; Insulin and glucagon are produced by the endocrine cells of the pancreas, and regulate blood sugar levels. HCl production (choice b) is regulated by gastrin, produced by the stomach itself. Blood calcium (choice c) is regulated by the thyroid and parathyroids. Bicarbonate secretion is regulated by secretin, produced by the small intestine. Regulation of blood pH (choice e) is complex, but the pancreas is not a significant player in this.
