Hemodynamics and Venous Return Quizlet
Hemodynamics and Venous Return Quiz
Test your knowledge on hemodynamics and venous return with our engaging quiz! This 10-question multiple-choice quiz is designed for anyone interested in understanding the dynamics of blood flow and vascular health.
Challenge yourself with questions covering key concepts such as:
- Blood vessel elasticity
- Factors determining blood viscosity
- Turbulent flow conditions
- Korotkoff sounds
Which blood vessel is the most elastic?
Aorta
Large artery
Arteriole
Medium sized artery
What is the most important factor determining the viscosity of whole blood??
Temperature
Gamma globulins
Clotting factors
Hematocrit
A decrease of this factor will increase resistance to blood flow:
Blood vessel length
Blood vessel radius
Blood vessel constriction
All of the above
Turbulent flow occurs when:
Blood flows through a narrow vessel
plasma protein levels are increased
Velocity of blood flow increases
None of the above
According to Bernoulli's principle, when blood passes through a narrowing in a blood vessel:
Blood flow slows down and pressure exerted on the vessel walls is low
Blood flow slows down but pressure on the blood vessel walls is high
Blood flow speeds up but pressure exerted on the vessel walls is low
Blood flow speeds up and pressure exerted on the vessel walls is high
A blood pressure of 160/50 implies that aortic compliance is:
Normal
Low
High
Which phase of the Korotkoff sounds occurs just before the silence?
3
4
5
6
What occurs when Vasopressin stimulates V1 receptors?
Renal sodium absorption
Arterial vasoconstriction
Angiotensin l is activated
Sodium excretion is increased
A pressure gradient of 10 mmHg driving venous return from peripheral veins to the heart is:
Normal
High
Low
Psf or MSP decreases when:
Venous compliance decreases
Venous compliance increases
Blood volume increases
