Ideally, blood should flow smoothly through the arteries in our bodies. When there are problems, or as a natural part of aging, there is an increased amount of resistance to blood flow. Viscosity is a term used to describe the thickness or stickiness of the blood and is directly related to this resistance, as are the radius and the length of the artery through which the blood flows. The formula given above relates the radius (r) of an artery to the viscosity (k), resistance (R), and length (of that artery. Which of the following represents the viscosity in terms of the other variables?
A.
B.
C.
D.
