AP PSYCHOLOGY

Detailed explanation-1: -Your adrenal glands make the hormone adrenaline and send it into your bloodstream. Adrenaline, a hormone your adrenal glands produce, has a purpose. It helps you face dangerous situations by causing temporary changes in your body. Your heartbeats and breathing get faster as part of the “fight or flight” response.

Detailed explanation-2: -Adrenaline, also called epinephrine, helps your body react more quickly to a threat. It makes the heart beat faster, increases blood flow to the brain and muscles, and stimulates the body to make sugar to use for fuel.

Detailed explanation-3: -Key actions of adrenaline include increasing the heart rate, increasing blood pressure, expanding the air passages of the lungs, enlarging the pupil in the eye (see photo), redistributing blood to the muscles and altering the body’s metabolism, so as to maximise blood glucose levels (primarily for the brain).

Detailed explanation-4: -Adrenaline and noradrenaline are dubbed emergency hormones or Fight or Flight hormones. These hormones are rapidly released in reaction to stress of any kind and during emergency situations. These hormones stimulate alertness, pupil dilation, piloerection (hair growth), perspiration, and other bodily functions.

Detailed explanation-5: -Adrenaline makes your blood vessels contract to direct your blood to major muscle groups. Adrenaline pumps more blood into your heart and muscles. The effects of adrenaline can last up to an hour after you’ve been removed from the stressful situation.
