Answer: Higher : Higher
Explanation: The total flow rate of blood is higher in the arterial system compared to the venous system because the pressure in the arterial system is higher than that of the venous system.
The velocity of flow is higher in arteries compared to veins of comparable size this is because the cross sectional area of the of arteries are smaller than that of the veins so the velocity is therefore higher. The smaller the cross sectional area, the higher the velocity.
