Question

How does adrenaline affects heart during emergency?​

Answer 1

Answer:

Adrenaline is also reffered to as flight of fight enzyme. It provides the body instant energy in cases like when you feel intense anger or fear. In this case this enzyme helps the heart to pump fast and provide oxygen to the various parts of the body for instant energy.

Answer 2

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. Adrenaline also triggers the blood vessels to contract to re-direct blood toward major muscle groups, including the heart and lungs
