Web24 de mai. de 2024 · Venous return is the flow of blood from the systemic venous network towards the right heart. At steady state, venous return equals cardiac output, as the venous and arterial systems operate in series. However, unlike the arterial one, the venous network is a capacitive system with a high compliance. WebNational Center for Biotechnology Information WebAt steady state conditions, cardiac output (CO) equals venous return. If CO did not equal venous return, then blood volume would collect in one part of the circulation or another. Therefore, since CO is 5 L/min, venous return also equals 5 L/min. + + + VASCULAR FUNCTION RELATIONSHIP + + fly to rapid city south dakota
