Most of the studies that have been done on body fluid flows do not consider density variations and compressibility effects.

This paper presents an analysis of the work that has been done on the physiological flows that occur in the human body and the models that have been proposed to model the ducts of the circulatory and respiratory system of the human body. The importance of the subject of gas dynamics for the solution of these flow problems is observed. It is seen how the Navier-Stokes equations can be used to determine the blood flow and pressure in the blood vessels, as well as to model the systemic arteries as a bifurcated tree of conformal and conical vessels.

A summary of the equations obtained from the asymmetric Navier- Stokes equations and a shock wave approximation is presented. In these works, which are based on the study of the gas dynamics of blood flow, the results obtained are verified by comparing the data of the models and simulations with data obtained by means of magnetic resonance or experimental studies.
