1. Calcium channel blockers, a type of anti-hypertensive drug, block the entry of calcium into smooth muscle which causes smooth muscle to relax. Explain how this decreases blood pressure. 2. Explain why cutting an arterial vessel will cause a greater loss of blood over the same amount of time than cutting a venous vessel.

E. Venous Blood Flow. 1. Blood flow through the venous system is only partially the result of heart action and instead also depends on skeletal muscle contraction, breathing movements, and vasoconstriction of veins. a. Contractions of skeletal muscle squeeze blood back up …

) wave result from slow flow of blood into the atria from the veins while tricuspid valve is closed. Figure (45). Figure (45): Normal jugular venous pulse (Ganong's review of medical physiology 2010). Venous return: The venous return (VR) is the amount of the blood flowing from the tissues into the veins and then into the right t atrium.

In the INDIRECT METHOD, no contact is made with the blood. Instead, pressure is applied externally to an artery occluding it and stopping blood flow. Then the blood pressure is determined by listening to various arterial sounds (KOROTKOFF SOUNDS) that result when the external pressure is reduced and the blood begins to flow again.

The site must be properly warmed prior to puncture. This increases arterial blood flow to the site up to sevenfold reducing the difference between the arterial and venous gas pressures. Inadequate warming of the site prior to the puncture will result in unreliable values. Fill two Radiometer safeCLINITUBES without allowing air bubbles to enter ...

Blood flow through the capillaries is determined by a combination of the driving force mean arterial pressure (MAP) and the amount of resistance in the arterioles. The rate of blood flow within a single capillary bed is proportional to the MAP and inversely proportional to the resistance of the arteriole regulating flow into that capillary bed.

Page 5. Blood Regulation and Mean Arterial Pressure • Similarly, as long as mean arterial pressure is normal, the various organs and body tissues of the body can regulate the amount of blood that enters them according to their needs at any given time. Page 6. Single Capillary Bed • Blood flow regulation occurs at the capillary beds.
