BIOC34H3 Chapter Notes -Pressure Overload, Diastole, Stroke Volume
Document Summary
Increase and decrease radius (1) via contraction of smooth muscle (1) under control of the ans (0. 5) 2 - viscosity is not an appropriate mechanism for normal flow control. * time to take effect is very long. 2 - altering tube length is not an appropriate mechanism for normal flow control. * can"t grow and retract blood vessel growth in an adult. 1 - pressure changes cause linear flow change. Radius changes cause exponential flow change (1) or radius change allows for local control (1). 3 - circle: esv sv edv top (skipped paragraph) more increase each (0. 5) 1 - athletes have increased stroke volume due to increased cardiac efficiency/ventricular hypertrophy/appropriate explanation. 2 - leaky aortic valve: left ventricle sv returns to left ventricle during diastole (1) volume and pressure overload (1; either) 2 - aortic valve constriction: left ventricular pressure overload (1). May mention that pulmonary bed is compromised, but it is not (-0. 5).
