The higher the degree of vascularization in a tissue, the greater the potential for local blood flow.
Indicate whether this statement is true or false.

Question 2) Tendons and ligaments have
A. a high degree of vascularization, therefore high perfusion and rapid healing.
B. a high degree of vascularization, therefore high perfusion and slow healing.
C. a high degree of vascularization, therefore low perfusion and slow healing.
D. a low degree of vascularization, therefore high perfusion and rapid healing.
E. a low degree of vascularization, therefore low perfusion and slow healing.

Question 3) If someone were to decrease their food intake and increase aerobic exercise, they might lose adipose tissue and condition their muscles. These changes would also influence their blood vessels, as there would be
A.
regression of blood vessels in adipose tissue and angiogenesis in skeletal muscle.
B. angiogenesis in both adipose tissue and skeletal muscle.
C.
regression of blood vessels in both adipose tissue and skeletal muscle.
D.
angiogenesis in adipose tissue and regression of blood vessels in skeletal muscle.
E. changes in the diameter of blood vessels, but no angiogenesis nor regression.

Question 4) Net filtration pressure (NFP) is equal to the
A. blood hydrostatic pressure minus the tissue hydrostatic pressure.
B. colloid osmotic pressure in the blood divided by resistance in the tissue.
C. blood pressure times the total peripheral resistance.
D. net hydrostatic pressure minus the net colloid osmotic pressure.
E. osmotic pressure in the tissue minus the hydrostatic pressure in the blood.

Question 5) If someone suffered from hypertension, such that the blood pressure in their capillaries was elevated, then net filtration pressure would be
A. above normal.
B. below normal.
(
Question 6) Give the formula for net filtration pressure; then include typical values (at the arterial end of a capillary bed) for all variables and include units.
What will be an ideal response?
(
Question 7) If someone were to have abnormally low levels of protein in their blood, then net filtration pressure would
A. be higher than normal.
B. be lower than normal.
(
Question 8) Which statement is accurate?
A. Filtration dominates at the arterial end of a capillary bed, and is driven by osmotic pressure.
B. Filtration dominates at the arterial end of a capillary bed, and is driven by hydrostatic pressure.
C. Filtration dominates at the venous end of a capillary bed, and is driven by osmotic pressure.
D. Filtration dominates at the venous end of a capillary bed, and is driven by hydrostatic pressure.

Question 9) Concerning the exchange between blood and interstitial fluid at systemic capillaries,
A. more fluid is absorbed and reabsorbed than is filtered.
B. more fluid is filtered than reabsorbed.
C. the fluid reabsorbed into the capillary exactly matches the amount filtered by the capillary.
(
Question 10) Blood colloid osmotic pressure is largely due to
A. the proteins in the blood, and it promotes reabsorption.
B. the high amount of water in the blood, and it promotes diffusion out of the capillaries.
C. the proteins in the blood, and it promotes filtration.
D. the pressure generated by the heart, and it favors osmosis into the arteriole end of the capillary bed.
E. the high amount of water in the blood, and it promotes filtration from arterioles.
