Mean arterial pressure is likely to decrease when Oblood viscosity decreases heart rate increases Ostroke volume increases blood vessel radius decreases end systolic volume increases

Inadequate tissue perfusion in hypovolemic shock occurs due to:   Question 9 options:   Decrease in cardiac blood flow due to valvular disease or pericarditis   Increase in intravascular volume leading to fluid volume overload   Decrease in intravascular volume leading to decreased cardiac output   Decrease in peripheral vascular resistance leading to decrease flow

Describe the process of auto-regulation as related to blood flow through capillary beds

aséd Vessel diameter Blood vessel Blood viscosity Obstructions length in vessels Which of the following will cause an increase in peripheral resistance? C

Explain the nature of blood flow and pressure regulation in the following system; the capillary system and venous system

Explain how the blood volume in the left ventricle changes throughout the cardiac cycle in response to changes in left atrial pressure, left ventricular pressure, and aortic pressure. Start with the relaxation of the ventricle at the beginning of diastole.

Discuss the events in an action potential that are generated in cardiac contractile cells.

Cardiomyopathy results in a thickened, hyperkinetic ventricular  heart muscle Hypertrophic Dilated Restrictive Obstructive

Clinical Corner: In speaking with his cardiologist, a high risk individual with angina pectoris during exercise was informed that his coronary blood flow is reduced. The most important variable that determines resistance to blood flow in his blood vessels is most likely:     increased viscosity of blood from not exercising.     the length of the blood vessel as he is a short individual.     the diameter of the vessel due to coronary artery disease.     increase blood pressure due to hypertension.

Precapillary sphincters are found in metarterioles and serve to: OPrevent blood from flowing backwards Provide a control point regulating blood flow into a capillary bed Increase pressure in a capillary bed None of the above
