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?
A) Hematocrit.
B) Cardiac output.
C) Arterial size.
D) Blood volume.
Blood Viscosity
A measure of the thickness and stickiness of an individual's blood, impacting how blood flows through vessels.
Hematocrit
The proportion of red blood cells to the total blood volume, expressed as a percentage, which is a key indicator of blood health.
Cardiac Output
The volume of blood the heart pumps through the circulatory system in one minute, a critical parameter in assessing heart health.

Final Answer :
A
Explanation :
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.
