How does our body respond when adrenaline is secreted in the body

A deer run fast when he sees a lion.

Adrenaline is an emergency hormone. Our body releases adrenaline when we are in danger or emergency.

Adrenaline prepares the body for swift action. It alerts the brain, increases muscle power, and reduces other works by performing the following actions:

  • Increase the blood flow to the brain by increasing (a)the heartbeat, (B)constricting blood vessels of the skin, (C)reducing blood flow to the intestine.
  • Increase the strength of the muscle by dilating the blood vessels of the muscle.
  • Release energy by promoting Glucose breakdown in the muscle cells and brain.
  • Lowers other workloads by slowing food digestion in stomach.
  • Removes extra weight of the body by relaxing the urinal sphincter.
