Question

as viscosity of the blood increases. multiple choice the pressure required to force it to flow increases. the pressure required to force it to flow decreases. the fluid becomes thinner. the hematocrit decreases. the flow does not change.

Explanation:

Viscosity is a measure of a fluid's resistance to flow. As blood viscosity increases, it becomes more resistant to flow, thus more pressure is needed to force it to flow. Higher - viscosity fluids are thicker, not thinner. Hematocrit is the percentage of red blood cells in the blood and is not directly related to the change in viscosity in the way described in the options. And an increase in viscosity would impede flow, not keep it the same.

Answer:

the pressure required to force it to flow increases.
