Document Summary
Pulmonary circulation: from the right ventricle blood is pumped to the capillary bed in the lungs, where carbon dioxide is replaced by oxygen, from the lungs, returns to the left atrium to complete systemic circulation. Smooth muscle layer on the arterioles near capillary bed: when muscles contract blood vessel is constricted. Ring of smooth muscles called precapillary sphincters close capillaries near the afferent arteriole: low pressure system. Blood flow is not a stationary fluid dynamic process. Ideal stationary fluid is: incompressible and deformable. Retained in dynamic case: fills container. Departure from smooth flow: no sound waves. Not retained flow has not reach mechanical equilibrium. Occurs with walls, or other adjacent objects. Interaction of fluid particles is limited to elastic conditions: laminar flow. Fluid flow that satisfies the first two assumptions. Expression of the conservation of mass or conservation of volume of an incompressible fluid. States that the volume flow rate is constant along a tube.
