blood pressure

the pressure of the circulating blood against the walls of the blood vessels; results from the systole of the left ventricle of the heart; sometimes measured for a quick evaluation of a person's health

gas pressure

the pressure exerted by a gas

head

the pressure exerted by a fluid

hydrostatic head

the pressure at a given point in a liquid measured in terms of the vertical height of a column of the liquid needed to produce the same pressure

IOP, intraocular pressure

pressure exerted by the fluids inside the eyeball; regulated by resistance to the outward flow of aqueous humor

oil pressure

pressure that keeps oil on the moving parts of an internal-combustion engine

osmotic pressure

(physical chemistry) the pressure exerted by a solution necessary to prevent osmosis into that solution when it is separated from the pure solvent by a semipermeable membrane

corpuscular-radiation pressure, radiation pressure

the minute pressure exerted on a surface normal to the direction of propagation of a wave

instantaneous sound pressure, sound pressure

the difference between the instantaneous pressure at a point in a sound field and the average pressure at that point

suction

a force over an area produced by a pressure difference

vapor pressure, vapour pressure

the pressure exerted by a vapor; often understood to mean saturated vapor pressure (the vapor pressure of a vapor in contact with its liquid form)

acoustic radiation pressure

(acoustics) the pressure exerted on a surface normal to the direction of propagation of a sound wave

air pressure, atmospheric pressure, pressure

the pressure exerted by the atmosphere

systolic pressure

the blood pressure (as measured by a sphygmomanometer) during the contraction of the left ventricle of the heart

diastolic pressure

the blood pressure (as measured by a sphygmomanometer) after the contraction of the heart while the chambers of the heart refill with blood

arterial pressure

the pressure of the circulating blood on the arteries

venous pressure

the pressure exerted on the walls of the veins by the circulating blood

hypertonicity

(of a solution) the extent to which a solution has a higher osmotic pressure than some other

hypotonicity

(of a solution) the extent to which a solution has a lower osmotic pressure than some other
