A. False It is higher in glomerular capillaries, as is necessary for filtration.

B. True Colloid osmotic pressure falls because the liver fails to synthesize enough albu-min.

C. False The reverse is true, causing transfer of tissue fluid into the circulation.

D. True Hence excess fluid is forced out of the capillaries into the interstitial spaces.
