Venous return is affected by several factors including muscle contraction, respiratory activity and gravity. Decreased venous compliance and vena cava compression also influence venous return. Other factors include valve competence, heartbeat, intrapericardial pressure, blood volume and degree of filling systematic circulation.
Venous blood pressure changes very little during the cardiac cycle, and is low, reflecting cumulative effects of peripheral resistance (17 mm Hg in venules dropping to almost 0 mm Hg at the termini of the venae cavae). Venous return is aided by both structural modifications and functional adaptations.
