superior vena cava
The heart has three surfaces: anterior, inferior and posterior. The anterior, sternocostal surface, the inferior or diaphragmatic surface and the base of the heart, the posterior surface.
Right Atrium
Anterior and posterior vena cavae are two collecting blood vessels,which open into right atrium of heart.They collect de-oxygenated blood from all the parts of the body.
the right atrium through the superior and inferior vena cava
Inferior vena cava
Right atrium receives de-oxygenated (without oxygen) blood from the superior and inferior vena cava. The superior vena cava brings blood from the top portion of the body mainly the neck, head etc. The inferior vena cava brings blood from the lower portion of the body like the abdomen, legs etc.
Inferior vena cava, aka posterior vena cava.
The function of the right atrium is to receive deoxygenated blood from the body (through the superior and inferior vena cavae, and the coronary sinus) and pump it into the right ventricle, which then pumps it to the lungs to be reoxygenated.

the ventricles
The coronary sinus opens into the right atrium, between the inferior vena cava and the superior vena cava.It returns the blood from the substance of the heart, and is protected by a ... Its wall is partly muscular, and at its junction with the great coronary vein is ... groove between the left atrium and ventricle on the posterior surface of the heart. ...
The inferior vena cava (or IVC), also known as the posterior vena cava, is the large vein that carries de-oxygenated blood from the lower half of the body into the right atrium of the heart.It is posterior to the abdominal cavity and runs alongside of the vertebral column on its right side (i.e. it is a retroperitoneal structure). It enters the right atrium at the lower right, back side of the heart.
