The adrenal gland produces adrenaline.


During strenous exercise,muscles use up energy at a quicker rate.In those situations the adrenal glands secrete the hormone adrenaline.Adrenaline stimulates the heart to pump blood more quickly so that glucose and oxygen can sufficiently reach the respiring muscles.

The hormone adrenaline is also associated with our survival reflexes.When we feel fear,we secrete adrenaline.We sweat more,blood is circulated away from the stomach and into the limbs.Our senses are sharpened.All these changes allow us to be more prepared to either attack or escape from the creature threating us.This is known as the 'fight or flight' reflex.Our body automatically prepares itself for a survival situation.Adrenaline stimulates the higher blood pressure that this reflex requires.
