Atrial
Atrial
Atrial (/ˈeɪtriəl/), derived from the Latin word "atrium", refers to the two upper chambers of the heart, known as the left and right atria. The term is often used in medical contexts to describe conditions, procedures, or aspects related to these chambers.
Etymology
The term "atrial" is derived from the Latin word "atrium", which was used in Roman architecture to refer to a central room or courtyard. In the context of the heart, the atria serve a similar central role, receiving blood from the body and lungs before it is pumped to the ventricles.
