  • Normal state of aortic semilunar valve
    The aortic semilunar valve is normally shut on the left side of the heart during ventricular diastole.
  • Definition of stroke volume
    Stroke volume is the amount of blood pumped by each ventricle in one heartbeat.
  • Dilated cardiomyopathy
    Dilated cardiomyopathy is a condition where the heart fails to pump blood effectively due to ventricular dilation.
  • Definition of afterload
    Afterload is the pressure the ventricles must overcome to eject blood during systole.
  • Type of capillaries in the spleen
    The spleen contains sinusoidal capillaries, which allow for the passage of large cells and blood components.
  • Ventricular diastole
    Ventricular diastole is the phase of the cardiac cycle when the ventricles relax and fill with blood.
  • Function of valves in veins
    Veins contain valves that prevent the backflow of blood and assist venous return to the heart.
