Text Solution

Verified by Experts

The correct Answer is:

Neural signals through the sympathetic nerves (part of ANS) can increase the rate of heart beat, the strength of ventricular contraction and thereby the cardiac output. Sympatetic nerves increase neartbeat by secreting noradrenaline/norepinephrine.
