Why does central venous pressure in the heart determine end diastolic pressure?
More importantly for me, why does end diastolic pressure determine end diasotlic volume (rather than volume determinine pressure)?
Thanks

Since two third of the blood is stored in venous system, end diastolic volume depends on venous compliance. When venous compliance increases, it elevates the capacitance of the veins. This in turn reduces venous returns and end diastolic volume.
