Answer 1

Adrenaline is known as the emergency hormone because it is released by the adrenal glands under the conditions of stress or excitement. This hormone is also a part of the body’s stress response called the fight or flight response. Adrenaline performs various functions in the body like:

• Increases the supply of oxygen and glucose to muscles and brain.
  
• Increases the heart rate and the amount of blood pumped by the heart per beat
  
• Dilates the air passages and constricts the blood vessels
