Osmosis occurs as water can cross the lipid bilayer through specialized channels for water movement called aquaporins.

Aquaporins are integral membrane water channels which form tetramers and have a function in transport of water between cells. Mutations in aquaporin genes have been associated with several human diseases, for example, diabetes insipidus.
