Question

What is the function of adrenaline hormone in the body ?

Answer 1

Adrenaline hormone which is also called as an emergency hormone or triple F hormone (FFF- Fight, Fright, Flight). It is produced in the medulla in the adrenal glands as well as some of the central nervous system's neurons. Within a couple of minutes during a stressful situation, it is quickly released into the blood, sending impulses to organs to create a specific response. The impact of adrenaline release in our body are as follows:

1. 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.
   
2. It also triggers the blood vessels to contract to re-direct blood toward major muscle groups, including the heart and lungs.
   
3. The body's ability to feel pain also decreases as a result of adrenaline.
4. Blood vessels dilate (enlarge) in our muscles.
5. Blood vessels constrict in our digestive tract to slow digestion.
6. Kidneys make more renin (to increase blood pressure).
7. Glucose production increases, for energy.
8. After the stress has subsided, adrenaline’s effect can last for up to an hour.
