Which of the Following is Not True About Blood Pressure

Question

Which of the following is not true about blood pressure?
A) The brachial artery is most commonly used to monitor blood pressure.
B) Blood pressure is higher in the arteries than in the capillaries.
C) Blood pressure is higher in the capillaries than in the veins.
D) Blood pressure is higher in the vena cava than in the arterioles.

Accepted Answer

Blood pressure is highest in the arteries, decreases as it moves through the capillaries, and is lowest in the veins. The vena cava is a large vein that carries deoxygenated blood back to the heart, so the blood pressure in the vena cava is lower than in the arterioles, which are small arteries that carry oxygenated blood away from the heart. Therefore, option D is not true.
