How does hydrostatics apply to blood pressure?

Hydrostatics is the branch of fluid mechanics studying fluids at rest and the pressure they exert. In medicine, hydrostatics is relevant to understanding blood pressure, which is the pressure of circulating blood against vessel walls. While most blood pressure results from the heart pumping, hydrostatic principles help explain fluid pressures within the circulatory system.

What we know

• Hydrostatic pressure is the static pressure exerted at a point of interest by the weight of a fluid column above it. [2]
• Hydrostatics is relevant to medicine in the context of blood pressure. [4]
• Blood pressure is the pressure of circulating blood against the walls of blood vessels, mostly resulting from the heart pumping. [3]
• Blood pressure is measured in millimetres of mercury above surrounding atmospheric pressure, or in kilopascals. [3]
