Solution 1

Adrenaline is often called the emergency hormone because it is released rapidly by the adrenal glands during stressful, fearful, or exciting situations to prepare the body for an immediate fight-or-flight response.

It prepares the body for action by:

  • Increasing heart rate and breathing rate to ensure more oxygen is delivered to the muscles.
  • Redirecting blood flow away from non-essential systems (like the digestive system) toward vital organs and skeletal muscles.
  • Increasing blood glucose levels by breaking down stored glycogen provides an immediate surge of energy to respond to the stressful situation.
