I can't understand this subject at all
please help me I can't correlate between right atrial pressure in each curve
I would be grateful if you help me

no problem I found a very good website which explains it simply and very well
 
It is intrinsically hard to understand this subject, because many textbooks including castanzo base their venous return curves off of guyton's work. It has been shown the work hardly correlates with the way we actually function, they are mechanistically flawed, and his interpretations and equations have consistently only led to confused thinking, even among physicians.

Also, the x and y axis for dependent and independent variables are wrong!

Thank god I found this paper before we started cardiac physiology:
http://ajpheart.physiology.org/content/301/3/H629.full.pdf+html

It's an eye opener, and the equations help me to really nail down the TRUE physiology.

you know, I don't actually understand why these curves are taught to us. If they don't make sense, we keep perpetuating them in medical student education?
