This article extensively covers the theoretical foundations of laminar and turbulent flows, which are basic concepts of fluid mechanics, and their practical importance in medicine.
The manifestation of these types of flow in the human body during blood circulation, the fact that in a healthy state the blood moves mainly in laminar flow and the occurrence of turbulent flow in pathological conditions, has been scientifically analyzed. The influence of narrowing of blood vessels, heart valve defects and changes in blood pressure on the nature of the flow has been considered. Also, the diagnostic value of determining the types of flow by the Reynolds number, methods for measuring blood flow velocity - Doppler ultrasound, angiography, MRI and CT methods - is described. The article reveals the important role of flow mechanics in the diagnosis and assessment of diseases of the cardiovascular system.
