Definition

Angiotonin is an older term for angiotensin, a hormone that raises blood pressure by constricting blood vessels. Think of it as an outdated synonym for a key blood pressure regulator. It's essentially the same thing as angiotensin, but less commonly used today. It highlights a historical aspect of medical terminology. This shows how science renames concepts as knowledge evolves. It is rarely used in modern medical literature.

Etymology

The word 'angiotonin' combines 'angio-' (vessel) and 'tonin' (related to tone or tension). It implies a substance that affects the tone of blood vessels. This reflects the early understanding of its function. 'Angiotensin' is now the preferred term.
