More Information

Atrial refers to the atrium, one of the upper chambers of the heart. These chambers are essential in the circulatory system as they receive deoxygenated blood and pump it into the ventricles, which then circulate it to the lungs or the rest of the body. In architecture, "atrial" describes a large, open, central space in buildings that allows for natural light and ventilation. This concept can be seen in both ancient Roman architecture and modern office buildings designed to foster openness and interaction.
