Exam 10: The Blood Vessels and Blood Pressure

The pulse pressure is the

Which of the following would promote an increase in blood pressure?

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 -Expanded plasma volume due to excessive fluid intake

Resistance to blood flow increases as the viscosity of the blood increases.

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 -Site of exchange of nutrients and waste products between the blood and surrounding tissues

During exercise, blood flow to the digestive tract is increased by dilation of the arterioles of the digestive tract.

The pulse pressure is the maximum pressure exerted in the arteries.

In an arteriole, if the blood vessel radius is 2 units and is then vasoconstricted to 1 unit,

As the total cross-sectional area of the vascular tree ____, the velocity of blood flow ____.

The primary mechanism for exchange of individual solutes across the capillary wall is ________________ down individual __________ gradients.

Plasma proteins are primarily responsible for the blood's viscosity, while the concentration of red blood cells greatly influences blood osmotic pressure.

Blood osmotic pressure is normally lower at the arteriolar end of a capillary than at the venular end.

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 pulse pressure?

Indicate whether arteriolar vasoconstriction or vasodilation would occur in the tissue in question by using the following answer code: a.produces vasoconstriction b.produces vasodilation c.no change in arteriolar caliber -Norepinephrine on cerebral arterioles

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 -Decreased rate of firing in afferent nerves reaching the cardiovascular control center ____ the parasympathetic nerve stimulation of the cardiovascular system.

Relaxation of arteriolar smooth muscle causes the radius of the vessel to _______________, a process known as ________________, whereas contraction of arteriolar smooth muscle causes the radius of the vessel to _______________, a process known as ______________.

Velocity of blood flow is the slowest in the veins because the blood must move uphill against gravity in these vessels.

If driving pressure is constant, flow will double when the radius increases by two-fold.

Hypertension occurs if the systolic/diastolic pressure is above the values of __________/__________.

Indicate whether arteriolar vasoconstriction or vasodilation would occur in the tissue in question by using the following answer code: a.produces vasoconstriction b.produces vasodilation c.no change in arteriolar caliber -Parasympathetic discharge on arterioles in the penis and clitoris
