The four chambers of the heart are Right Atrium, Left Atrium, Right Ventricle, Left Ventricle.
The right atri.um is located in the upper right corner of the heart superior to the right ventric.le (superior to the right ventricle and anteromedial to the left atrium)
The left atriu.m is located in the posterior aspect of the right at.rium, next to the superior vena cava (superior to the left ventric.le, posterolateral to the right at.rium, posterior to the aortic root, and anterior to the esophagus)
The right ven.tricle is located in the lower right portion of the heart below the right at.rium and opposite the left ventri.cle (extends from the right atri.um to the ape.x of the heart)
The left ven.tricle is located in the bottom left portion of the heart below the left atr.ium, separated by the mit.ral valve (in a posterior and lateral location relative to the right ven.tricle)
Sorry for the periods in between the words, it kept saying it contained innappropriate words even though it didn't
