The posterior part of the right atrium consists of the sinus venarum cavarum (atrial sinus).
At the ostium cavea superioris and inferioris, the two Vv. cavae (superior and inferior) merge.
From these the blood can flow seamlessly into the atrium without intermediate valves. The fossa ovalis is located above the entrance of the V. cava inferior and is surrounded by the limbus fosssae ovalis. The Crista terminalis delimits the anterior part (right atrium with cardiac ear) from the posterior part.
The right atrium is larger than the left and is also part of the low pressure system. In contrast to the smooth-walled front part of the atrium, the rear part has much more structure.
