WebThe fraction of the column composed of red blood cells relative to the entire column is the hematocrit, which normally is in the range of 40%. The upper portion is yellowish plasma. Red blood cells carry oxygen. Blood with a low hematocrit (e.g., 20%) leaves the tissues relatively oxygen-starved and weak. Web25 mei 2000 · As hematocrit decreased, the greater volume fraction of the diluent caused the samples to behave rheologically more like the corresponding pure diluent and less like whole blood. For the neat diluents themselves, at shear rates ≤ 45 s −1 , the viscosity of 5% albumin and plasma were strongly shear rate dependent.
