Exam 10: The Blood Vessels and Blood Pressure

Indicate which type of vessel performs the function listed by writing the appropriate letter in the blank using the answer code below. a.arteries b.arterioles c.capillaries d.veins e.lymphatics -Changes in the radius of this vessel type regulate the distribution of the cardiac output to various areas of the body

For a blood pressure reading of 136/78, the 78 refers to the pressure in the major arteries when the heart's ventricles are relaxing.

For the following questions, choose the appropriate letter from the answer code below to make the statement true. a.increases b.inhibits or decreases c.has no effect on -Increasing sympathetic nerve activity ____ vein radii, and decreasing vein radii ____ venous return.

Indicate which type of vessel performs the function listed by writing the appropriate letter in the blank using the answer code below. a.arteries b.arterioles c.capillaries d.veins e.lymphatics -Major resistive vessels

A major function of the arteries is to serve as a blood reservoir.

The sphygmomanometer and stethoscope can be used for a direct measurement of arterial blood pressure.

Which factor would reduce total peripheral resistance?

If the blood pressure is recorded as 118/76, indicate the correct value of the pressure in question by writing the appropriate letter in the blank using the following answer code: a.118 mm Hg b.42 mm Hg c.97 mm Hg d.76 mm Hg e.90 mm Hg -What is the mean arterial pressure?

The interstitial fluid is not part of the ECF.

What is the most important factor that increases blood flow through a tissue to meet that tissue's needs?

Because the capillaries have the smallest radii of any vascular segment, they are the major resistive vessels.

The receptors for the baroreceptor reflex are located in the ____________________ and ____________________.

Which of the following alterations could lead to edema?

Sympathetic stimulation of veins ____ venous pressure and drives ____ blood into the heart.

The integrating center for baroreceptor reflexes is the ____________________ located in the ____________________ part of the brain.

Which of the following does not cause relaxation of smooth muscle within local arterioles?

Match the term with the correct characteristic. a.reactive hyperemia b.active hyperemia c.pressure autoregulation d.extrinsic control -Increase in blood flow to a tissue that occurs after removal of an occlusion of its blood supply

Vasogenic shock is triggered by widespread ____________________ of blood vessels.

Organs that recondition the blood

Indicate what effect the change in question would have on bulk flow using the answer code below: a.increases ultrafiltration and decreases reabsorption b.decreases ultrafiltration and increases reabsorption c.increases both ultrafiltration and reabsorption d.decreases both ultrafiltration and reabsorption e.would not alter ultrafiltration and reabsorption -Reduced synthesis of plasma proteins due to liver disease
