Question

Explain briefly, why adrenaline is called the emergency hormone?

Answer 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.

Answer 2

Adrenaline is called the emergency hormone because it is released during stress or fear to trigger the fight-or-flight response, rapidly preparing the body for action by increasing heart rate, breathing rate, and blood glucose levels.
