Question

As arterial blood reaches typical capillaries in the body, its hydrostatic pressure is approximately:

Answer 1

The maximum arterial pressure reached during peak ventricular ejection is called systolic pressure. The minimum arterial pressure occurring just before ventricular ejection is called diastolic pressure. Pulse pressure is the difference between systolic and diastolic pressure. The 3 main factors in determining the magnitude of pulse pressure are stroke volume, speed of ejection of the stroke volume, and arterial compliance. Arteriosclerosis is a condition in which arteries are less compliant, in which the arteries stiffen that progresses with age and increases pulse pressure. Another term, mean arterial pressure, is the average pressure in the arteries at any given time, which is expressed by diastolic pressure plus 1/3 pulse pressure.
