n. (context physiology English) The formation of bubbles of gas in biological fluids due to reduced environmental pressure.


Ebullism is the formation of gas bubbles in bodily fluids due to reduced environmental pressure, for example at high altitude. It occurs because a system of liquid and gas at equilibrium will see a net conversion of liquid to gas as pressure lowers, for example, liquids reach their boiling point at lower temperatures when the pressure on them is lowered.
