In the absence of peripheral arterial occlusive disease, the systolic pressure is greater in the tibial arteries than in the abdominal aorta. ____

Question

Quizplus · Accepted Answer

The systolic blood pressure normally increases as blood moves from central (aorta) to peripheral (limb) regions. Resistance to flow is higher in the small-diameter tibial arteries than in the large-diameter aorta, resulting in a pressure gradient between the two vessel systems. Therefore, ankle pressures normally are equal to or slightly greater than systemic pressure.
