Question

Give 2 functions of adrenaline

Answer 1

Answer:

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