Detailed explanation-1: -Adrenaline (epinephrine) is a hormone your adrenal glands make to help you prepare for stressful or dangerous situations. Adrenaline rush is the name for the quick release of adrenaline into your bloodstream.

Detailed explanation-2: -It alerts the hypothalamus, which sends a message to the adrenal glands to give you an instant burst of adrenaline, the “action” hormone. Adrenaline causes your heart to race and pump more blood to your muscles.

Detailed explanation-3: -Adrenaline is a hormone released from the adrenal glands and its major action, together with noradrenaline, is to prepare the body for ‘fight or flight’.

Detailed explanation-4: -What is the Function of Adrenaline? Adrenaline triggers the body’s fight-or-flight response. This reaction causes air passages to dilate to provide the muscles with the oxygen they need to either fight danger or flee.

Detailed explanation-5: -The adrenal medulla, the inner part of an adrenal gland, controls hormones that initiate the flight or fight response. The main hormones secreted by the adrenal medulla include epinephrine (adrenaline) and norepinephrine (noradrenaline), which have similar functions.
