The structure of the vessel wall depends on hemodynamic conditions: blood flow velocity, volume and blood pressure. Arteries located close to the heart are characterized by a predominance of elastic elements that are able to counteract high hemodynamic parameters. As you move away from the heart, hemodynamic values decrease, the caliber of blood vessels decreases and the number of muscle elements in their walls increases, which are able to create additional force to push blood into the network of the smallest vessels.
