noun
osmotic pressure
Scientific term used in physiology and physics to describe the pressure required to prevent osmosis across a semipermeable membrane.
細胞膜を介した水の移動は浸透圧によって決まる。
The movement of water across the cell membrane is determined by osmotic pressure.
Compound of 浸透 (shintō, 'osmosis, permeation') and 圧 (atsu, 'pressure'). The term is a direct calque of the English 'osmotic pressure'.
