10 Questions2 MinutesCreated by FlowingRiver321

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?

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
