Epinephrine is a hormone and neurotransmitter which belongs to the catecholamine\'s family. It is secreted by the human body in case of stress or during a physical activity. Secretion of epinephrine in the human body increases heart rate and contraction strength of the heart and provokes a higher blood pressure. Epinephrine is secreted by adrenal glands to respond to an immediate and increasing need of energy. Epinephrine is mostly diffused in the blood, and its action generally doesn\'t exceeds 2 minutes.
