Steady-state venous return: residue in a recent model analysis of the notion that it is driven by elastic recoil of the venous system.

to the editor: I have argued ([1][1]–[3][2]) against interpreting Guyton's findings as revealing that steady-state venous return (Q) is driven through the resistance of the venous system, Rvs, by the difference between mean systemic pressure (Pms) and right atrial pressure (Pra). Despite previous
