Match the types of vessel, labelled a. through e., with the function(s) they perform. (Options may be used more than once or not at all.) a.arteries b.arterioles c.capillaries d.veins e.lymphatics -serve as low-resistance passageways from the heart to the tissues

Which of these factors does NOT cause arteriolar vasodilation?

What does microcirculation comprise?

Decreased sympathetic nerve activity _____ the arteriolar radius.

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

Which of these roles is NOT a function of the lymphatic system?

Primary hypertension refers to chronically elevated blood pressure of unknown origin.

Which of these conditions is NOT a complication of uncontrolled hypertension?

Match the effects, labelled a. through e., that the changes in question would have on bulk flow. (Options may be used more than once or not at all.) a.The change would increase ultrafiltration and decrease reabsorption. b.The change would decrease ultrafiltration and increase reabsorption. c.The change would increase both ultrafiltration and reabsorption. d.The change would decrease both ultrafiltration and reabsorption. e.The change would not alter ultrafiltration and reabsorption. -escape of plasma proteins into the interstitial fluid due to capillary damage

Which of the following is NOT a compensation mechanism for blood loss?

The two hormones involved primarily in fluid balance and that are also potent vasoconstrictors are ____________________ and ____________________.

Match the arteriolar effects, labelled a. through c., with the tissues in question. (Options may be used more than once or not at all.) a.would produce arteriolar vasoconstriction b.would produce arteriolar vasodilation c.would not cause any change in arteriolar calibre -occlusion of an artery supplying a particular tissue

As metabolic activity of an organ or tissue increases, blood flow to that organ increases. What is the term for this phenomenon?

Match the effects, labelled a. through d., with the events in question. (Options may be used more than once or not at all.) a.increase BP b.decrease BP c.increase heart rate only d.have no effect on BP or heart rate -adrenalin release

As the concentration of red blood cells increases in the blood, the viscosity of the blood increases.

Which of the following will NOT cause an increase in blood pressure?

Normally capillary filtration exceeds reabsorption by about ____________________ litres daily.

The category of controls known as ____________________ (local or extrinsic) is responsible primarily for matching tissue blood flow with the metabolic needs of the specific tissue involved.
