cardiovascular system Flashcards
starting from the left atrium, explain the pathway of blood
left atrium, bicuspid valve, left ventricle, semi-luna valve, aorta, BODY, vena cava, right atrium, tricuspid valve, right ventricle, semi-luna valve, pulmonary artery, LUNGS, pulmonary vein, left atrium
how do you calculate cardiac output?
HR X SV
how to calculate stroke volume from end systole and diastole volume
EDV-ESV
what’s heart rate (HR) and its units
number of times your heart beats per minute, bpm
what’s stroke volume (SV) and its units
the volume of blood that you can eject from the left ventricle per beat, ml
what’s cardiac output (Q) and its units
the volume of blood that you can eject from the left ventricle per minute, L/min
what’s systole and diastole in simple terms?
systole- heart contracting
diastole- heart relaxing
what’s end-diastolic volume (EDV)?
the volume of blood in the ventricles at the end of the relaxation filling stage
what’s end-systolic volume (ESV)?
the volume of blood remaining in the ventricles at the end of the contraction phase
