EVERYDAY SCIENCE

Detailed explanation-1: -Adrenaline (epinephrine) is a hormone your adrenal glands send through your bloodstream. When you’re scared or stressed suddenly, adrenaline is quickly sent into your body. This is commonly known as an adrenaline rush because it happens so fast.

Detailed explanation-2: -Epinephrine (Adrenaline) and Norepinephrine (Noradrenaline) Among other things, these hormones are capable of increasing the heart rate and force of heart contractions, increasing blood flow to the muscles and brain, relaxing airway smooth muscles, and assisting in glucose (sugar) metabolism.

Detailed explanation-3: -Also called adrenaline, epinephrine increases blood pressure and heart rate when the body is under stress.

Detailed explanation-4: -A sudden large increase in adrenal hormones is called an adrenergic crisis (AC). AC causes severe high blood pressure (hypertension) and a rapid heart rate (tachycardia).

Detailed explanation-5: -Aldosteronism. The adrenal glands produce too much of the hormone aldosterone. This makes the kidneys retain salt and water and lose too much potassium, which raises blood pressure.
