1) The adjustment of blood flow to each tissue in proportion to its requirements at any point in
time is termed autoregulation.
True or False? - True
2) Arterial pressure in the pulmonary circulation is much higher than in the systemic circulation
because of its proximity to the heart.
True or False? - False
3) Osmotic pressure is created by the presence in a fluid of small diffusible molecules that easily
move through the capillary membrane.
True or False? - False
4) The cerebral arterial circle (circle of Willis) is an arterial anastomosis.
True or False? - True
5) The outermost layer of a blood vessel is the tunica intima.
True or False? - False

True or False? - True
8) A precapillary sphincter is a cuff of smooth muscle that regulates the flow of blood into the
capillaries.
,True or False? - True
9) The carotid sinus reflex protects the blood supply to the brain, whereas the aortic reflex is
more concerned with maintaining adequate blood pressure in the systemic circuit as a whole.

fluid, bulk flow is more important for regulation of the relative volumes of blood and interstitial
fluid.
