• C. A) Deoxygenated blood B) Oxygenated air
• D. A) Oxygenated blood B) Deoxygenated blood

Answer 1

The correct option is B

A) Deoxygenated blood

B) Oxygenated blood

The right auricle receives deoxygenated blood from different parts of the body and sends it to the right ventricle. From the right ventricle, the deoxygenated blood is carried to the lungs for oxygenation by the pulmonary artery. The oxygenated blood from the lungs returns to the left auricles via the pulmonary veins.
