Question

How does adrenaline prepare the body to deal with situation. 2marks​

Answer 1

Answer:

Key actions of adrenaline include increasing the heart rate, increasing blood pressure, expanding the air passages of the lungs, enlarging the pupil in the eye (see photo), redistributing blood to the muscles and altering the body's metabolism, so as to maximise blood glucose levels (primarily for the brain).

Answer 2

Answer:

It reduces the blood to the digestive system and skin; as a result the blood further reaches the skeletal muscles. All these responses together prepare the body to deal with the emergency situations.
