stroke volume
|
volume acutallyh pumped from ventricle with each ventricular systole
depends on/is affected by EDV |
|
end diastolic volume
|
EDV amount of blood in ventricle at the end of ventricular filling of diastole
|
|
frank starling law of the heart
|
larger the EDV, the more increase in contractile strength
|
|
afterload
|
stroke volume- amount of periphial resistance the hart has to pump against
increased afterload- decreased SV |
|
end systolic voume
|
ESV- amount of blood in ventricle after ventricular systole
|
|
ejection fraction
|
percentage ESV ejected ad stroke volume (about 50-60% of EDV)
SV/EDV x 100 |
|
cardiac output
|
rate at which a primarily left ventricle pumps blood- must be even at both sides of the heart or it would back up... expressed as volume per unit time
|
