Chp 5 Frank-Starling's Law of the Heart, Windkessel Elements & Conservation of Volume

Question 1

define Diastolic

Answer 1

relaxation and filling phase. State of High Compliance, low stiffness.

Question 2

define Systolic

Answer 2

contraction and ejection phase. State of Low Compliance, high stiffness.

Question 3

define Isovolumic Contraction

Answer 3

beginning of systolic period, end of diastolic, when ventricular volume is the same, but higher contraction force and no change in volume yet.

Question 4

define Isovolumic Relaxation

Answer 4

beginning of diastolic period, end of systolic; when ventricle relaxes.

Question 5

what is formula for pressure using Hooke’s Law?

Answer 5

Ph = (Vh - V0) / Ch

Question 6

define Frank-Starling’s Law of the Heart?

Answer 6

“The heart will pump out all of the blood that is returned to it within the limits of the heart.”
