'arterial' originates from Latin, specifically the word 'arterialis,' where 'arteria' meant 'windpipe or artery.'

'arterialis' transformed into the Old French word 'arterial,' and eventually became the modern English word 'arterial' through Middle English.

Initially, it meant 'pertaining to windpipes or arteries,' but over time it evolved into its current meaning of 'relating to arteries.'
