Vedclass · Answer

(A) The correct answer is $A$. $A$ special neural center in the medulla oblongata can moderate cardiac function through the autonomic nervous system $(ANS)$. Neural signals through the sympathetic nerves (part of $ANS$) increase the rate of heartbeat,the strength of ventricular contraction,and thereby the cardiac output. Conversely,parasympathetic neural signals (another component of $ANS$) decrease the rate of heartbeat,the speed of conduction of action potential,and thereby reduce the cardiac output.
