Vedclass · Answer

(C) The regulation of cardiac activity is primarily controlled by the autonomic nervous system $(ANS)$.Specifically,the medulla oblongata contains specialized centers that regulate heart rate and blood pressure.When blood pressure is high,the body needs to reduce it by slowing down the heart rate and dilating blood vessels.This is achieved through the $Cardio-inhibitory$ center,which decreases the heart rate,and the $Vasodilation$ center (or inhibition of the vasoconstriction center),which relaxes the blood vessels to lower the pressure.Therefore,the correct combination for regulating high blood pressure is the $Cardio-inhibitory$ and $Vasodilation$ centers.

During high blood pressure,the regulation of circulation and heart rate is controlled by which of the following centers?
