The thickness or viscosity of the blood affects the ease with which blood flows through small vessels.Examining what value might help determine the amount of blood viscosity?

Question

Quizplus · Accepted Answer

The hematocrit,or the percentage of red blood cells in the blood,determines blood viscosity.Blood pressure also depends on the cardiac output or volume pumped by the heart,but cardiac output does not affect viscosity.Differences in arterial size help modify blood pressure;the smaller lumen of a vessel increases vascular resistance but does not affect viscosity.Blood volume also affects blood pressure,but it does not directly affect viscosity.
