Abstract
Chronic venous disease is a vascular disorder characterized by impaired venous return and a progressive dysfunction of the venous system. Pathological reflux can occur due to abnormal dilation and weakening of the vein wall. The circulatory system is a natural structure in which physical laws, such as the law of closed containers and gravity, operate. The malfunctions in the system also adhere to these laws of nature. This article explains how the principles of fluid dynamics apply to the flow of blood in the veins of the legs. I am discussing the principles of Pascal's law, Torricelli's law, Bernoulli's law, and Poiseuille's law, and how they are relating to the anatomy and physiology of the venous system.
期刊介绍:
Vasa is the European journal of vascular medicine. It is the official organ of the German, Swiss, and Slovenian Societies of Angiology.
The journal publishes original research articles, case reports and reviews on vascular biology, epidemiology, prevention, diagnosis, medical treatment and interventions for diseases of the arterial circulation, in the field of phlebology and lymphology including the microcirculation, except the cardiac circulation.
Vasa combines basic science with clinical medicine making it relevant to all physicians interested in the whole vascular field.
