Verified step by step guidance
1
Understand the role of the pancreas in regulating blood glucose levels. The pancreas produces several hormones that help maintain glucose homeostasis.
Identify the hormones produced by the pancreas: insulin, glucagon, somatostatin, and pancreatic polypeptide.
Learn the function of each hormone: Insulin decreases blood glucose levels by facilitating the uptake of glucose into cells. Glucagon increases blood glucose levels by promoting the release of glucose from the liver. Somatostatin regulates the secretion of other pancreatic hormones. Pancreatic polypeptide influences the regulation of pancreatic secretions.
Focus on insulin: It is the primary hormone responsible for lowering blood glucose levels. It acts by promoting the uptake of glucose into muscle and fat cells and inhibiting glucose production in the liver.
Conclude that among the options provided, insulin is the hormone that lowers blood glucose levels, as it directly facilitates the reduction of glucose concentration in the bloodstream.
