the cardiovascular system: measuring blood pressure
when taking blood pressure, inflate the cuff so that blood flow is _____ in the blood vessel.
constricted
when you don't hear any sounds, this is recorded as the ___________ pressure
diastolic
mean arterial pressure (MAP) is the calculated average pressure in the arteries. It is closer to the diastolic pressure because the heart spends more time in _______. Write the equation for pulse pressure: MAP=____________
-diastole -diastolic pressure + 1/3 pulse pressure
______ pressure (DP) is the lowest pressure in the artery and is a result of ventricular _______ . Normal DP is about ______.
-diastolic -diastole -80 mmHg
Blood flow is generated by the _____. blood pressure results when that flow encounters______ from the vessel walls.
-pumping action of the heart -resistance
open the valve slowly, releasing the pressure. the first sound you hear through the stethoscope is recorded as the __________ pressure
-systolic
the maximum pressure exerted by blood against the artery wall is known as ______ pressure (SP) and is the result of ventricular_______
-systolic -systole
pulse pressure (PP) is the difference between _____ pressure and _____ pressure.Write the equation for pulse pressure: PP=______________
-systolic -diastolic -SP-DP = PP
blood flows in layers within the lumen of blood vessels within the layers in the middle of the lumen flowing fastest. This is known as _______ flow.
laminal
blood pressure is expressed in _______ of mercury and is written as mmHg.
mm
blood pressure fluctuates with each heartbeat. The pulse you feel in your wrist is a _______ created by the contracting heart ejecting blood.
pressure wave
the sounds you hear are due to the _________ of the blood
turbulent flow
what does the dicrotic notch represent
when the aorta is closed
normal (SP) is about _________ mmHg
120
