Hemodynamic disorder

Hemodynamics refers to the mechanics of blood flow in the cardiovascular system. It mainly studies blood flow, blood flow resistance, blood pressure, and their relationships. Blood is a fluid, so the basic principles of hemodynamics are the same as those of general fluid mechanics. However, because the vascular system is a relatively complex elastic pipeline system, blood is a liquid containing various components such as blood cells and colloidal substances, not an ideal liquid. Therefore, hemodynamics has both the generality of general fluid mechanics and its own characteristics.
