What is the role of the adrenal glands?

• A. Secreting insulin
• B. Producing growth hormones
• C. Regulating stress response and metabolism
• D. Filtering blood

Answer: (C)

The adrenal glands play a crucial role in the body's response to stress and in regulating metabolism. They produce a variety of hormones, including cortisol, which helps manage stress levels by regulating metabolism and the immune response. Cortisol is released during stressful situations and aids in maintaining homeostasis by influencing how the body converts fats, carbohydrates, and proteins into energy.

Additionally, the adrenal glands produce adrenaline (epinephrine) and norepinephrine, which are key players in the "fight or flight" response, preparing the body to react to perceived threats. This includes increasing heart rate, blood pressure, and energy supplies.

In contrast, insulin secretion is primarily the function of the pancreas, and growth hormones are produced by the pituitary gland. Filtering blood is a function of the kidneys, not the adrenal glands. Thus, the correct answer specifically highlights the adrenal glands' vital functions in stress regulation and metabolic processes.
