Which organ produces epinephrine and norepinephrine?

The adrenal glands are responsible for producing epinephrine and norepinephrine, which are crucial hormones involved in the body's stress response. These hormones are released into the bloodstream during times of stress or danger, preparing the body for a "fight or flight" response. Epinephrine, also known as adrenaline, increases heart rate, dilates air passages, and enhances blood flow to muscles, while norepinephrine works to increase alertness and arousal, and it also plays a role in blood vessel constriction which helps maintain blood pressure.

The presence of these hormones is vital for managing acute stress situations, as they help the body react quickly and efficiently to threats. The adrenal glands, located on top of the kidneys, comprise the medulla and cortex, with the medulla being specifically responsible for the secretion of epinephrine and norepinephrine. This makes them the correct answer to the question regarding the production of these key hormones.
