Venoconstriction ________ the amount of blood within the venous system,which ________ the volume in the arterial and capillary systems.

Question

Quizplus · Accepted Answer

Venoconstriction reduces the amount of blood within the venous system, which decreases the volume in the arterial and capillary systems. This is due to a redistribution of blood from the venous system to the arterial and capillary systems, which results in a decrease in venous return and a subsequent decrease in cardiac output. Therefore, the correct choice is B, which indicates a reduction in venous blood volume and an increase in arterial and capillary blood volume.
