The hormones secreted by pancreas serves to

Analyze the question: It asks about the function of hormones secreted by the pancreas.

Explain the concept: The pancreas is both an exocrine gland (it secretes digestive enzymes) and an endocrine gland. Its endocrine part is made up of the islets of Langerhans, which secrete two hormones:

• Insulin (from beta cells): lowers blood glucose by helping cells take up glucose and by converting excess glucose to glycogen in the liver and muscles.
• Glucagon (from alpha cells): raises blood glucose by converting glycogen back to glucose.

Together, they keep blood sugar level stable (homeostasis).

Check each option:

• A. Facial hair development: This is controlled by androgens such as testosterone, from the testes. It is not a pancreatic function.
• B. Raise blood calcium: This is done by parathyroid hormone from the parathyroid glands, not the pancreas.
• C. Lower blood glucose level: This is the action of insulin, the main pancreatic hormone. Correct.
• D. Make the body react to emergencies: This describes adrenaline (epinephrine) from the adrenal medulla, the "fight or flight" hormone.

Answer: The pancreas secretes insulin, which lowers blood glucose.

Exam tip: Match each gland to its key job:

• Pancreas → blood sugar (insulin lowers it)
• Adrenal → emergencies (adrenaline)
• Parathyroid → calcium
• Testes → male features, such as facial hair

Insulin = "Insulin brings sugar in" to the cells, so blood sugar goes down.
