Hemodynamics

（重定向自Hemodynamic phenomena）

Illustration demonstrating how vessel narrowing, or vasoconstriction, increases blood pressure.

An anesthetic machine with integrated systems for monitoring of several hemodynamic parameters, including blood pressure and heart rate.

Hemodynamics or hæmodynamics (hemo- + -dynamics) is the fluid dynamics of blood flow. The circulatory system is controlled by homeostatic mechanisms, much as hydraulic circuits are controlled by control systems. Hemodynamic response continuously monitors and adjusts to conditions in the body and its environment. Thus hemodynamics explains the physical laws that govern the flow of blood in the blood vessels. The relationships can be challenging because blood vessels are complex, with many ways for blood to enter and exit under changing conditions.
