end systolic volume
is the volume of blood in each ventricle at the end of ventricular systole (amount of blood left in heart)
volume of blood pumped by a ventricle per beat/contraction
stroke volume determine by
is the amount of blood returning to the heart via vena cavae
assistance from skeletal muscle, thoracic pump-breathing brings blood to the heart & valves
detect blood pressure in the aortic sinus and carotid sinus
help monitor and regulate blood pressure
physical force exerted against a surface by a liquid
aka blood pressure
forces fluid out of the capillaries by filtration
is determined by the cardiac output and peripheral resistance
force and the amount of blood pumped
end diastolic volume
(EDV) the volume of blood in each ventricle at the end of ventricular diastole (relaxation of ventricle)
amount of blood in ventricles prior to contraction (volume)
-determined by EDV & Venous return
- if increase preload then increase force of contraction
period of time the wave of depolarization is delayed in the AV node while the atria contract
period of time between the depolarization of the ventricles and repolarization of ventricles. this is the time the ventricles are contracting
