4 valves preventing reflux Tricuspid
Pulmonic semilunar
Mitral (bicuspid)
Aortic semilunar
Cardiac Output (CO) = heart rate (HR) x stroke volume (SV)
stroke volume amount of blood pumped out of ventricle in a single
beat.
60 to 130 mL
cardiac output Volume of blood pumped by heart per minute.
3 components of CO - preload
- afterload
- contractility
normal CO range 4-8 L/min
preload VOLUME of blood in ventricles at end of diastole
afterload RESISTANCE L ventricle must overcome to eject
blood.
