This lecture is about Normal venous return curve, which shows that in a normal person the amount of blood returning to the heart every minute is around 5 liters per minute but if the right atrial pressure starts increasing then the venous return starts decreasing.
if right atrial pressure reaches 7mmHg the venous return becomes zero, and this pressure level is considered as Mean systemic filling pressure.
