description: The given work is devoted to blood flow through vessels of various geometries. The main equation used to solve the problem is the Navier-Stokes equation. Blood viscosity was considered as a variable, depending on the shear rate and the level of hematocrit. The finite volume method was used to calculate the characteristics of the blood flow in various blood vessels, including vessels of variable cross section. The results were compared with existing experimental data on the example of a capillary, and also it was analyzed how the aggregation of red blood cells and their organization in the blood flow affects the discrepancy between calculations and experiment. Also the influence of hematocrit on the blood-velocity profile is shown in given work and the changes occurring in the blood flow during narrowing of the blood vessel are considered.
