This work provides a description of the principles of thephysics of fluid dynamics related to vascular ulcers. The morphological characteristics of thecardiovascular system promote blood flow. The contraction force of the left ventricle is enhancedby its ability to reduce its radius of curvature and by increasing the thickness of the ventricular wall(Laplace’s Law). Arterial flow must overcome vascular resistance (Ohm’s equation). The elasticnature of the artery and the ability to reduce its diameter as flow rate progresses facilitate bloodconduction at high speed up to arteriolar level, and this can be determined by the second equationof continuity. As it is a viscous fluid, we must discuss laminar flow, calculated by the Reynoldsnumber, which favors proper conduction while aiming at the correct net filtration pressure. Anyendothelial harmful process that affects the muscle wall of the vessel increases the flow speed,causing a decrease in capillary hydrostatic pressure, thus reducing the exchange of nutrients at theinterstitial level. With regard to the return system, the flow direction is anti-gravity and requiresendogenous aid to establish the Starling’s equilibrium. Knowledge on the physics of vascular fluiddynamics makes it easier to understand the processes of formation of these ulcers so as to choosingthe optimal healing and prevention techniques for these chronic wounds.
