Variations in the resistivity of blood can give valuable clues to changes in the blood's viscosity...

Variations in the resistivity of blood can give valuable clues to changes in the blood's viscosity and other properties. The resistivity is measured by applying a small potential difference and measuring the current. Suppose a medical device attaches electrodes into a 1.5-mm-diameter vein at two points 5.0 cm apart. What is the blood resistivity if a 8.8 V potential difference causes a 230 μA current through the blood in the vein? Express your answer in ohm meters.
