उत्तर
Adrenaline hormone is secreted by the adrenal medulla. It prepares the body to meet any emergency situation for "fight" - i.e., to face danger, or for "flight" to run away from it.
Its functions are:
- It increases heart beat accompanied by an increase in blood pressure.
- It increases blood supply to the muscles while decreasing it to the skin and visceral organs.
- More glucose is released into the blood by the liver (like putting more fuel into the engine)
