Morphology

coronary + sinus

The meaning is directly compositional: 'coronary' relates to the heart and 'sinus' denotes a venous or vascular channel, so a learner who knows both constituents can infer a venous channel in the heart that collects blood. This noun–noun compounding follows ordinary English formation patterns (and similar terms exist cross-linguistically), making the term transparent to learners.

Etymology

Coronary sinus comes from old words: coronary means 'crown' because the heart's blood vessels run around the heart like a crown, and sinus means 'bay', a small curve where blood can gather. That is why the name fits the short vein that sits around the heart and collects blood to return it to the right atrium.
