Polycythemia Has a Direct Effect on Which of the Following

Question

Polycythemia has a direct effect on which of the following factors that influence blood pressure?
A) blood volume
B) strength of the heart contraction
C) heart rate
D) blood viscosity

Accepted Answer

Polycythemia is a condition that results in an increase in the number of red blood cells in the blood, which leads to an increase in blood viscosity. Blood viscosity refers to the thickness or stickiness of the blood, which can affect blood flow and ultimately blood pressure. Therefore, polycythemia has a direct effect on blood viscosity, which is a factor that influences blood pressure.
