Answer:
When a person is stressed or frightened, the adrenal gland releases a flood of hormones, such as adrenaline and cortisol. These hormones increase the heart and respiratory rate, elevate blood pressure, boost energy supplies, sharpen concentration and slow down other body processes so the body can run from or fight a threat.
