Question 6

___ capillaries are very porous and allow high volumes of fluids to pass through them, whereas, ___ capillaries consist of more tightly joined cells that allow a high degree of selective materials to pass

Answer 6

fenestrated, continuous

Question 7

compared to arteries, the velocity of flow of the blood through the capillaries is

Answer 7

much lower

Question 8

If capillary hydrostatic pressure was 35 mm Hg and blood colloid osmotic pressure was 40 mm Hg what is the net filtration pressure (mm Hg)? What does this number mean?

Answer 8

The net filtration pressure (NFP) represents the interaction of the hydrostatic and osmotic pressures, driving fluid out of the capillary. It is equal to the difference between the CHP and the BCOP. Since filtration is, by definition, the movement of fluid out of the capillary, when reabsorption is occurring, the NFP is a negative number.
