Oxygen poor blood returns from the body to the heart through superior Vena cava and inferior Vena cava, the two veins that bring the oxygen poor blood back to the heart. This oxygen poor blood enters the right atrium or right upper chamber of the heart.
ANAmarendra:
Why not right ventricle?
The entire blood of right ventricle is coming from right auricle only .
yes it is the same. The oxygen poor blood from right auricle flows through the tricuspid valve and enters the right ventricle . Therefore, the answer is right auricle and right ventricle ,as it receives oxygen poor blood or deoxygenated blood through anterior and posterior vena cava.
Hope you understood
