"WebVenous Return - Hemodynamics. Venous return (VR) is the flow of blood back to the heart. Under steady-state conditions, venous return must equal cardiac output (CO) when averaged over time because the cardiovascular system is essentially a closed loop (see figure). Otherwise, blood would accumulate in either the systemic or pulmonary circulations. " - Involved in the regulation of stroke volume
