During the cardiac cycle shown in the graph above the ventricles eject _______ of the blood they contain at the beginning of systole.   A a little less than half   B a little more than half    C nearly all (more than 95%)    D 120ml

The normal blood pressure for an adult is less than 120/80. How does the resting systolic/diastolic pressure of your volunteer compare to the normal value?

If pulse pressure is calculated to equal 40 mm Hg and diastolic pressure is 70 mm Hg, then systolic pressure must have been __________.   30 mm Hg    90 mm Hg    110 mm Hg    140 mm Hg    none of the above

The pco2 in the aorta is  a 40mmhg b 46mmHg c 100 mmHg

____ is the contractile phase of the cardiac cycle and _____ is the relaxation phase of the cardiac cycle

This abnormal ECG indicates: A ventricular fibrillation B premature ventricular contractions (PVCs) C ST-segment elevation D premature atrial contractions (PACS) hahah

The coronary arteries arise from the __________.   A right atrium   B inferior vena cava   C aorta   D superior vena cava   E pulmonary trunk

When the ventricles contract with more force this causes the _____ volume to be larger and the ____ volume to be smaller.   A end diastolic; stroke   B stroke; end systolic   C end systolic; end diastolic

The resting EKG of this patient lets us know that the patient has , 0.11 s 0.50 s bradycardia tachycardia 1st degree AV block a healthy heart with no apparent problems

Which valves are closed during isovolumetric contraction & isovolumetric relaxation of the ventricles?   A bicuspid & tricuspid   B aortic & pulmonary semilunar   C none of the valves   D all of the valves
