-For this capillary bed, which of the following statements is correct?

A) The pH is lower on the arterial side than on the venous side.
B) Oxygen is taken up by the erythrocytes within the capillaries.
C) The osmotic pressure remains constant due to carbon dioxide compensation.
D) The hydrostatic pressure declines from the arterial side to the venous side because oxygen is lost.
E) Fluids will leave the capillaries on the arterial side of the bed and re-enter on the venous side.
