A)Plasma proteins decrease blood viscosity,so blood flows smoothly.
B)The normal pH range of blood is 7.35 to 7.45.
C)Blood viscosity contributes to normal blood pressure.
D)Oxygen has a greater effect on blood pH than does carbon dioxide.

Question

B) The normal pH range of blood is indeed 7.35 to 7.45.
C) Blood viscosity is one of the factors that contributes to normal blood pressure. However, plasma proteins actually increase blood viscosity, not decrease it (as stated in answer choice A). Oxygen and carbon dioxide both have important effects on blood pH, so answer choice D is incorrect.
