Answer 1

6. The blood in the superior vena cavae is CO2 rich is the correct answer.  The superior vena cava is the largest vein that carries deoxygenated blood the major organs head, arms, chest, and neck to right auricles.

7. The blood in the right ventricle is CO2 rich is the correct answer. The deoxygenated blood from the right atrium receives from the right ventricle and then this blood is pumped into the lungs pulmonary circulation for oxygenation.

8. The blood passes 2 valves to reach the lungs from the right side of the heart. The Blood reaches the lungs through the pulmonic valve which opens into the pulmonary artery for final arrival.

9. Blood found in the aorta is O2 rich is the correct answer. It is the main artery of the heart which carries blood to all parts of the blood from the heart. It delivers oxygen-rich blood to the body.

10. In the pulmonary veins, the blood is O2 rich is the correct answer. The pulmonary veins pump oxygenated blood to the heart from the lungs.
