Hematocrit varies depending on location within the body. For example, the hematocrit values in the spleen and kidney are 75 and 20, respectively. Assume that two veins, one from each organ, join together. Given the information in the Table below, what are the diameter of the spleen vein and the velocity of the kidney vein? Hematocrit for kidney and spleen veins Velocity (cm/s) Diameter (mm) Hematocrit (-) Spleen vein 4 75 Kidney vein 0.25 20 Joined vein 5 0.28 40
