'arterialisation' originates from English, specifically from the verb 'arterialise' (also spelled 'arterialize' in US English'), where 'arteri-' comes from Latin 'arteria' meaning 'artery' and the suffix '-ise/-ize' means 'to make' plus '-ation' forming a noun.

'arterialisation' developed from the verb 'arterialise/arterialize,' which in turn derives from Latin 'arteria' (via Medieval Latin). The modern English noun was formed by adding the nominalizing suffix '-ation' to the verb.

Initially it meant 'to make like an artery' in a general morphological sense; over time it has become a specialized medical term referring to the physiological or structural conversion of vessels or tissues to arterial characteristics.
