Question 6

In an investigation into the physiological control of blood water potential, researchers studied the effect of a new loop diuretic (Compound H-12) on renal blood flow.

The mean rate of flow of blood plasma into the kidneys was measured for three groups of participants:

Group A (High-dose Compound H-12): the mean plasma flow rate was 450 cm³ min^-1.
Group B (Low-dose Compound H-12): the mean plasma flow rate was 395 cm³ min^-1.
Group C (Control): the mean plasma flow rate was 334 cm³ min^-1.

The mean rate of flow of blood plasma is 58% of the mean rate of flow of whole blood into the kidneys.

Calculate how much greater the total volume of whole blood flowing into the kidneys is for Group A (High-dose) than for Group C (Control) over the 5 hours of the monitoring period. Give your answer in $cm3\text{cm}^3$ .
