Morphology

angiotensin + II

The meaning is directly derivable from the constituents: 'angiotensin' (a blood-vessel-constricting hormone) combined with the Roman numeral 'II' signals the second form or isoform of that hormone. This numeric labeling of sequential molecular forms is a regular, cross-linguistic naming convention, so a learner who knows both constituents can infer the MWE's meaning.

Etymology

Angiotensin II gets its name from parts that show its job: angio means 'vessel', tensin means 'to tighten', and II means 'second'. So the name gives a picture of a second form that makes blood vessels 'tighten' and so 'raise blood pressure'.
