AYTR-ee-uh-m/ˈeɪtriəm/

An atrium is an upper chamber of the heart that receives blood: the left atrium; atrial. It is also a high open hall inside a building: a glass atrium. Ventricle is the pumping chamber; hall is everyday for the building. Label the left atrium on the heart diagram. Mix-up: atrium vs atrium as a brand; auditorium; do not write atrium for a corridor with a low ceiling unless the plan labels it.
