Given the risk, the adrenal glands secrete adrenaline, which relaxes the muscles of the airways to allow more air to enter the lungs, stimulates the heart and makes it beat faster and harder, the pupils dilate to increase the ability to observe, the respiration rate increases and slows the digestive system so that more blood to enter the muscles, which increases stress and blood pressure.
