- 3. The lower right chamber, pumping deoxygenated blood to the lungs through the pulmonary artery.
- 5. The upper left chamber, receiving oxygenated blood from the lungs through the pulmonary veins.
- 8. The upper right chamber, receiving deoxygenated blood from the body through the superior and inferior vena cava
- 10. The wall separating the right and left ventricles.
- 12. The inner layer of the heart wall, lining the heart chambers and valves.
- 13. The two upper chambers of the heart, receiving blood from the body and lungs.

Down
- 1. The outer layer of the heart wall, also known as the visceral pericardium, fused to the heart.
- 4. The lower left chamber, pumping oxygenated blood to the body through the aorta.
- 6. The thick, muscular middle layer of the heart wall, responsible for pumping blood.
- 7. The valve between the right atrium and right ventricle, preventing backflow of blood.
- 9. The sac that surrounds the heart, protecting it and providing lubrication. It consists of a fibrous outer layer and a serous inner layer.
