Vedclass · Answer

(D) Cardiac activity is regulated by both neural and hormonal mechanisms.$1$. Intrinsic regulation: The human heart is myogenic,meaning it is auto-regulated by specialized nodal tissues ($SA$ node and $AV$ node).$2$. Neural regulation: $A$ special neural center in the medulla oblongata can moderate cardiac functions through the autonomic nervous system $(ANS)$. Sympathetic nerves increase the rate of heartbeat,while parasympathetic nerves decrease it.$3$. Hormonal regulation: Hormones secreted by the adrenal medulla,such as adrenaline and noradrenaline,increase cardiac output and heart rate.Therefore,all the given statements are correct.
