So we know that along the inferevenicaver, we have the partially oxygenated blood that is moving along and eventually moves into the right atrium of the heart. But before it moves into the right atrium of the heart, the partially oxygenated blood that moves along the inferior venecrava eventually combines with the deoxygenated blood that is moving along the superior venecave and which is coming from the extremities found on the upper side of that developing Fetus. So we have the deoxygenated blood is moving along our superior venecaa. It eventually combines and mixes with the blood that is coming from this, the inferior venecrava. So we have the partially oxygenated blood is moving along the inferior venecrava, and eventually it combines and it goes into the right atrium of the heart. Now, once inside the right atrium of the heart, what does the blood do next?
