Vedclass · Answer

(D) The regulation of cardiovascular functions is primarily managed by the medulla oblongata in the brain.When blood pressure is high,the body needs to reduce it by slowing down the heart rate and dilating the blood vessels.This is achieved through the cardio-inhibitory center,which decreases the heart rate,and the vasodilation center,which relaxes the blood vessels to lower peripheral resistance.Therefore,the correct mechanism involves cardio-inhibitory and vasodilation centers.

During high blood pressure,the regulation of circulation and heart rate is controlled by .......

$A$: The resting heart rate,about $75$ beats/minute,is usually lower than the autorhythmic rate of the $SA$ node ($90-100$ beats/minute).
$R$: At rest,the parasympathetic nervous system effects dominate the heart rate.

Neural signals through ............ can increase the rate of heart beat,the strength of ventricular contraction and thereby the cardiac output.

Assertion $(A) :-$ Parasympathetic neural signals decrease the cardiac output.
Reason $(R) :-$ Parasympathetic neural signals decrease the rate of heartbeat and the speed of conduction of action potentials.
