Vedclass · Answer

(D) The heartbeat is regulated by the autonomic nervous system and hormonal factors.Sympathetic nerves stimulate the heart to increase the rate of heartbeat.Epinephrine (also known as Adrenaline) is a hormone secreted by the adrenal medulla that increases the heart rate and force of contraction.Acetylcholine,on the other hand,is a neurotransmitter that slows down the heart rate.Therefore,sympathetic nerves and epinephrine are the factors that stimulate or increase the heartbeat.
