hormone and neurotransmitter involved in the fight-or-flight response

Epinephrine, also known as adrenaline, is a hormone and neurotransmitter produced by the adrenal glands. It plays a crucial role in the body's "fight-or-flight" response by increasing heart rate, expanding air passages in the lungs, and redistributing blood to muscles, which helps the body respond to stressful situations.
