Quizplus · Accepted Answer

Adrenaline (also known as epinephrine) is a hormone secreted by the adrenal glands that can bind to receptors on the heart and increase heart rate and stroke volume. This physiological response helps to overcome the increased systemic vascular resistance and augmented blood volume. Glucose, calcitonin, and insulin are not directly involved in this response.
