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.
The walls of the blood vessels restrict where blood can flow, thereby creating friction as the blood flows against the walls. Two factors of blood vessels walls effect blood flow resistance: = Blood vessel length: The longer a blood vessel, the more resistance the blood will encounter as it flows. Blood vessel length is fixed, and therefore resistance due to blood vessel length is constant, in the adult.
