Adrenaline (also known as epinephrine) is a hormone and neurotransmitter that is produced by the adrenal glands and certain neurons in the central nervous system. It is released into the bloodstream in response to stress or danger, preparing the body to respond to the perceived threat.

Adrenaline acts on various organs and tissues in the body, producing a range of physiological responses. Some of the main effects of adrenaline include:

Increased heart rate and blood pressure: Adrenaline stimulates the heart to beat faster and harder, increasing blood flow to the muscles and other organs.
Dilation of airways: Adrenaline relaxes the smooth muscles in the airways, allowing more air to flow into the lungs.
Increased blood sugar levels: Adrenaline triggers the liver to release stored glucose into the bloodstream, providing a quick source of energy for the body.
Constriction of blood vessels: Adrenaline constricts blood vessels in certain parts of the body, directing more blood flow to the muscles and brain.
These physiological responses prepare the body to respond to stress or danger, enabling a "fight or flight" response. Adrenaline can also be used in medical settings to treat severe allergic reactions (anaphylaxis), cardiac arrest, and other emergency situations.

Answer: Adrenaline (epinephrine) is a hormone your adrenal glands make to help you prepare for stressful or dangerous situations. Adrenaline rush is the name for the quick release of adrenaline into your bloodstream. This gets your body ready for a “fight or flight” response.

Adrenaline makes your heart beat faster and your lungs breathe more efficiently. It causes the blood vessels to send more blood to the brain and muscles, increases your blood pressure, makes your brain more alert, and raises sugar levels in the blood to give you energy.
