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 law states that blood flow is proportional to the fourth power of the vessel's internal radius. Therefore, if a blood vessel's radius doubles in size due to vasodilation, the blood flow through the vessel will increase 16 fold. Blood flow can be regulated to individual organs, or it can be considered in total. Total peripheral resistance is defined as the total resistance to flow of blood in the systemic circulation. The arterioles are important regulators of blood flow because of their smaller size and muscular walls.
