Explanation:
Detailed explanation-1: -For example, adrenalin (epinephrine for our American cousins) is a hormone released by the adrenal gland above the kidneys. But the target tissues for adrenalin are found all over the body – e.g. the heart, the skeletal muscles, the iris in the eye, the hairs in the skin, the lungs, the liver etc.
Detailed explanation-2: -What is the Function of Adrenaline? 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.
