Why 1 the NFP at the venous end a negative number filtration
     Why 1$ the NFP at the venous end a negative number?  filtration occurs not reabsorption  fluid moves from the capillary to the interstitial space  the intercellular fluid moves out of the capillaries  reabsorption occurs not filtration 
  
  Solution
The net filtration pressure (NFP) (CHP - BCOP) at the venous end is negative number, because here the reabsorption takes place and the capillary hydrostatic pressure (18 mm Hg) is less than the blood osmatic pressure (25 mm Hg). So, 18-28 = -7. Due to this the intracellular fluid moves out of the capillaries.
Thus, the correct option is (c).
