Adrenaline (also known as epinephrine) is a hormone and neurotransmitter produced by the adrenal glands, which are located on top of the kidneys. It plays a crucial role in the body’s “fight or flight” response to stress.
When the body is under stress, such as during a physical threat, adrenaline is released into the bloodstream. Adrenaline increases heart rate, blood pressure, and respiration, while also directing blood flow to the muscles, lungs, and brain. This allows the body to respond quickly and efficiently to the threat.
Adrenaline can also be released in response to emotional stress, such as anxiety or fear, and can produce similar physiological responses. In addition to its role in the stress response, adrenaline is also used in some medical treatments, such as in the treatment of anaphylaxis (a severe allergic reaction) or cardiac arrest.
