Morphology

atrium + dextrum

The phrase is compositionally transparent: 'atrium' denotes the upper heart chamber and 'dextrum' is the Latin root meaning 'right', so together they straightforwardly indicate the right atrium. Although 'dextrum' is a Latin form and not common in everyday English, anatomical terminology routinely uses Latin/Greek roots across languages, so a learner who knows both constituents would readily infer the meaning.

Etymology

Atrium dextrum comes from old doctors who used Latin words: atrium meant an 'entrance hall' and dextrum meant 'right'. So the term names the heart's 'right entrance hall', meaning the right upper chamber that receives blood from the body.
