Midterms Quizzes (lab) Flashcards
The total quantity of blood that can be stored in a given portion of the circulation for each mmHg pressure rise
Vascular Compliance
The quantity of blood that moves through a specific point in the circulation over a specific time period, and expressed as volume over time
Vascular Flow
The efficiency of the ventricles in emptying itself through the ejection period
Ejection Fraction
Which of the following statements is CORRECT regarding the ventricular volume and pressure changes during a cardiac cycle?
i. Ventricular Filling - Increase Ventricular Volume and Pressure
ii. Isovolumetric Contraction - Increase Ventricular Volume and Pressure
iii. Ejection - Decrease Ventricular Volume, Increase Ventricular Pressure
iv. Isovolumetric Relaxation - Decrease Ventricular Volume, Increase Ventricular Pressure
Statement i and iii
Which of the following statements is CORRECT regarding Frank-Sterling Mechanism of the heart?
A. This is the ability of the heart to adapt to increasing volumes of inflowing blood
B When the heart muscle is stretched during filling, the greater is the force of contraction
C. Within physiological limits, the heart pumps all blood that return to it by way of the veins
D. All statements are correct
