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).
What happens when you have adrenaline?
Adrenaline triggers the following changes in the body: increasing the heart rate, which may lead to a feeling of the heart racing. redirecting blood toward the muscles, causing a surge in energy or shaking limbs. relaxing the airways to give the muscles more oxygen, which may cause breathing to become shallow.
