The function of the right atrium is to act as a receiving and concentrating chamber for blood returning to the heart from its trip through the body systems. This blood is low in Oxygen and high in carbon dioxide. When the atrium contracts (beats) it sends its bolus of blood into the right ventricle of the heart which in turn will send the blood on to the lungs.
Artium Museum was created in 2002.
The opening between the right and left atrium is the foramen ovale. The duct connecting the pulmonary artery to the aorta is the ductus arteriosus.
Vena Cava
The partition between the sides of the heart is called the septum.
