What is meant by arterial pressure (MAP)?

Question

Quizplus · Accepted Answer

Arterial pressure, also known as mean arterial pressure (MAP), is the average pressure throughout each cardiac cycle. It is calculated as diastolic pressure plus one-third of the difference between the systolic and diastolic pressures. Choice A is incorrect because it only refers to the pulse pressure, not MAP. Choice B is partially correct as arterial pressure can be affected by the tone of the arterial walls, but it does not fully capture what MAP represents. Choice D refers to the formula for calculating MAP but does not provide a definition for it.
