Answer 2

Epinephrine or adrenaline sometimes spelled "epinephrin" or "adrenalin" respectively, is a hormone and a neurotransmitter. Epinephrine is a catecholamine, a sympathomimetic monoamine derived from the amino acids phenylalanine and tyrosine. The Latin roots ad-+renes and the Greek roots epi-+nephros both literally mean "on/to the kidney" (referring to the adrenal gland, which secretes epinephrine). Epinephrine is sometimes shortened to epi in medical jargon.

Epinephrine plays a central role in the short-term stress reaction—the physiological response to threatening, exciting or environmental stressor conditions such as high noise levels or bright light. It is secreted by the adrenal medulla. When released into the bloodstream, epinephrine binds to multiple receptors and has numerous effects throughout the body. It increases heart rate and stroke volume, dilates the pupils, and constricts arterioles in the skin and gut while dilating arterioles in leg muscles. It elevates the blood sugar level by increasing hydrolysis of glycogen to glucose in the liver, and at the same time begins the breakdown of lipids in adipocytes. Epinephrine has a suppressive effect on the immune system.

An adrenal gland sits on top of each kidney in a person. When a person feels fear, anger, or excitement, the adrenals release chemicals called hormones into the blood. One of those hormones is called adrenaline.

It helps us to fight or run away. Digestion is switched off. The heart beats faster. Blood clots more easily, useful if we get cut in a fight.
