Which side of the heart pumps The right side of the heart pumps deoxygenated blood to the lungs, where the
deoxygenated blood to the lungs, and blood releases CO₂ and becomes higher in oxygen before returning to the left side
what happens to the oxygen levels there? of the heart.
What is cardiac preload? volume of blood in the ventricle at the end of diastole
1. hypervolemia
preload is increase in 2. regurgitation of cardiac valves
3. heart faliure
What is cardiac afterload? the resistance the ventricle must overcome to pump blood out of the heart
afterload increased in hypertension and vasoconstriction
increased afterload = increased cardiac output
Volume of blood that stretches the ventricle at the end of diastole, just before onset
preload
of systole
preload gives us the =ventricular end-diastolic volume
and is determined by Determined by venous return (=volume of blood entering the RA)
Force that the contracting heart muscle must generate to eject blood from the filled
afterload is
ventricles
afterload is affected by peripheral vascular resistance and wall tension
Define contractility in the context of the Contractility is the ability of the myocardium to stretch and contract in response to
heart. the filling of the heart with blood.
Stroke volume is the amount of blood within the ventricle that is ejected with each
What is stroke volume?
contraction.
Left Ventricular Ejection Fraction Measures the percentage of blood leaving the left ventricle each time it contracts.
What does it measure
