The cardiac activity could be moderated by the autonomous neural system.
Tick the correct answer.
(a) The parasympathetic system stimulates heart rate and stroke volume
(b) The sympathetic system stimulates heart rate and stroke volume
(c) The parasympathetic system decrease the heart rate but increase stroke volume
(d) The sympathetic system decreases the heart rate but increases stroke volume

(b) The sympathetic system stimulates heart rate and stroke volume
(c) The parasympathetic system decrease the heart rate but increase stroke volume
(d) The sympathetic system decreases the heart rate but increases stroke volume
Option (b) The sympathetic system stimulates heart rate and stroke volume
Neural is signals through the sympathetic nerves can increase the rate of the heart beat, the strength of ventricular contraction and thereby stimulating the cardiac output. Hence, sympathetic system is involved in stimulating heart rate and stroke volume. Therefore, other options are wrong.
