Which two pancreatic hormones closely control the levels of glucose in the blood?
A
Thyroxine and calcitonin
B
Aldosterone and renin
C
Insulin and glucagon
D

Verified step by step guidance1
Identify the primary function of the pancreas in the endocrine system, which is to regulate blood glucose levels.
Understand that the pancreas releases hormones that help maintain glucose homeostasis in the body.
Recognize that insulin and glucagon are the two key hormones produced by the pancreas that directly influence blood glucose levels.
Insulin lowers blood glucose levels by facilitating the uptake of glucose into cells, while glucagon raises blood glucose levels by promoting the release of glucose from stored glycogen in the liver.
Compare the roles of other hormones mentioned (thyroxine, calcitonin, aldosterone, renin, adrenaline, and cortisol) and note that they do not primarily regulate blood glucose levels like insulin and glucagon do.
