exercise 19

when the semilunar valves are open during a cardiac cycle, what occurs

I, II, IV, and V I- atrioventricular valves are closed II- ventricles are in systole IV- blood enters the aorta V- blood enters the pulmonary trunk

the two distinct heart sounds, described phonetically as lubb and dupp represent

blood turbulence associated with the closign of the atrioventricula and semilunar valves

which of the following statements is not true

both systolic and diastolic blood pressures can be obtained via the pulse method

the artery that is normally used to evaluate blood pressure is the

brachial artery

systole and diastole of both atria pulse systole and diastole of both ventricles is called

cardiac cycle

the heart has an intrinsic regulating system called the cardiac

conduction system

the period of the cardiac cycle when all valves are closed and pressure continues to climb withing the left venricle is called the period of

isovolumetric contraction

rapping or thumping sounds heard clinically when blood pressure is being taken are called

korotkoff sounds

the typical ECG produces three clearly recognizable waves, the first wave which indicates depolarization of the atria is called the

p wave

the difference between systolic and diastolic pressure is called

pulse pressure

although the pulse may be detected in most surface arteries, pulse rate is usually determined on the

radial artery of the wrist

heart sounds provide valuable information about the

valves

an average blood pressure value for an adult is

120/80

an average pulse pressure is

40 mm Hg

when ventricular pressure drops below atrial pressure, which phase of the cariac cycle occurs

atrial systole

various up and down impulses produced by an ECG are called

defelection waves

electrical impulses accompanying the cardiac cycle are recorded by

electrocardiograph

abnormal or peculiar heart sounds are called

murmers

during which phase of the cardiac cycle are all four chambers in diastole

relaxation period

the instrument normally used to measure blood pressure is called a

sphygmomanometer
