Etymology
'angiotonin' originates from Greek, specifically the words 'angeion' meaning 'vessel' and 'tonos' meaning 'tension', with the suffix '-in' indicating a substance.
'angiotonin' was coined in the early 20th century in scientific literature to describe a substance that increases vascular tension, and is now more commonly referred to as 'angiotensin'.
Initially, it meant 'a substance that increases the tension of blood vessels', and this meaning has remained consistent, though the term 'angiotensin' is now more widely used.
