hydrostatic pressure

hy·dro·stat·ic pres·sure

the pressure exerted by a liquid as a result of its potential energy, ignoring its kinetic energy; frequently used to distinguish a true pressure from an osmotic pressure or to emphasize the variation in pressure in a column of fluid due to the effect of gravity.

hydrostatic pressure

the pressure exerted by a liquid.

hydrostatic pressure

The pressure exerted by a fluid within a closed system.
See also: pressure


pertaining to a liquid in a state of equilibrium or the pressure exerted by a stationary fluid.

hydrostatic pressure
a significant factor in intestinal absorption; the tissue fluid pressure against which osmosis has to achieve a positive gradient if small molecules are to pass the cell membranes and be absorbed.
