Question

Quizplus · Accepted Answer

Epinephrine is a hormone that activates the sympathetic nervous system, which increases heart rate, constricts blood vessels, and elevates blood pressure. It can also increase GI tract activity, but this is a secondary effect to its primary actions on cardiovascular and respiratory systems. Epinephrine effects are short-lived, typically lasting only a few minutes to an hour. Therefore, option A is not true. Option C and E are incorrect as epinephrine increases heart rate and is a product of the sympathetic nervous system.
