Adrenaline

  1. 1. Adrenaline Maria Bouzaid
  2. 2. What is? Adrenaline is a hormone produced by the adrenal glands during high stress or exciting situations. This powerful hormone is part of the human body's acute stress response system, also called the "fight or flight" response.
  3. 3. Where are the adrenal glands? The adrenal glands are found directly above the kidneys in the human body (7.62 cm in length). Adrenaline is one of several hormones produced by these glands. Along with norepinephrine and dopamine, it is a catecholamine, which is a group of hormones released in response to stress. These three hormones react with various body tissues, preparing the body to react physically to the stress causing situation.
  4. 4. How it works? It works by stimulating the heart rate, contracting blood vessels, and dilating air passages, all of which work to increase blood flow to the muscles and oxygen to the lungs.
  5. 5. For what can be used? Additionally, it is used as a medical treatment for some potentially life-threatening conditions including anaphylactic shock. In the US, the medical community largely refers to this hormone as epinephrine, although the two terms may be used interchangeably.
  6. 6. When it happens? When a person is in a dangerous situation, the hypothalamus in the brain alarms the adrenal glands to release adrenaline and other hormones directly into the bloodstream. The body's systems react to these hormones, giving the person a nearly instant physical boost. Strength and speed both increase, while the body's ability to feel pain decreases.
