Which function is associated with adrenal glands as endocrine glands?

• A. Stress response to fight or flight
• B. Metabolism regulation
• C. Glucose metabolism
• D. Oxygen transport

Answer: (A)

Adrenal glands release hormones into the bloodstream that prepare the body for quick action. Their most recognizable role is the stress response, or fight-or-flight, powered by adrenaline (epinephrine) and norepinephrine. These hormones rapidly raise heart rate and blood pressure, dilate airways, and mobilize energy stores like glucose to supply muscles during a perceived threat. Metabolism regulation and glucose metabolism are influenced by adrenal hormones, but they are broader effects and part of longer-term adjustments, not the immediate, defining action of the glands in this context. Oxygen transport isn’t a function of the adrenal glands at all; that’s handled by red blood cells.
