검증된 단계별 안내1
Step 1: Understand the role of the pancreas in blood glucose regulation. The pancreas secretes several hormones that help maintain blood glucose levels within a narrow range.
Step 2: Identify the hormones secreted by the pancreas: insulin, glucagon, somatostatin, and pancreatic polypeptide, each with distinct functions.
Step 3: Recognize that insulin is secreted when blood glucose levels are high to promote glucose uptake by cells, lowering blood glucose.
Step 4: Know that when blood glucose levels fall, the hormone glucagon is secreted to raise blood glucose by stimulating glycogen breakdown and glucose release from the liver.
Step 5: Conclude that the pancreatic hormone secreted to increase blood glucose concentration when it falls is glucagon.
