Which gland release epinephrine and when is epinephrine released circumstances?

Epinephrine, also known as adrenaline, is released by the adrenal medulla, which is part of the adrenal glands located on top of each kidney. This hormone is typically released in response to stress or danger, as part of the body's "fight or flight" response, during situations such as physical threats, intense exercise, or emotional stress. The release of epinephrine leads to increased heart rate, elevated blood pressure, and enhanced energy availability, preparing the body to react quickly.
