Solution
During emergency or dangers, adrenal gland secretes adrenaline. It is a hormone secreted directly into the blood and is transported to different parts of the body. It speeds up the heartbeat and hence supplies more oxygen to the muscles for fight or flight. It dilates the pupil to increase the area of vision. This results in an increase in the rate of breathing and blood pressure which enables them to fight in such urgent situation. It also dilates the bronchus thereby increasing the volume of air available for diffusion.
