Thorax - transverse section

You selected: right atrium

Venous blood from the body enters the right atrium. Blood from the head, neck and arms collects in the superiour vena cava while blood from the lower regions of the body collects in the inferior vena cava.

Blood subsequently enters the right ventricle where it will be pumped to the lungs for oxygenation. The tricuspid valve regulates the flow of blood between the two chambers.
