How does blood flow Deoxygenated

Deoxygenated blood:

Super/Inferior Vena Cava→ Right Atrium → Aortic Valve→ Right ventricle→ Pulmonary Valve → Pulmonary trunk→ Arteries → Lungs → oxygenated

How does blood flow oxygenated

Lungs→ Pulmonary veins→ Left Atrium → Left ventricle → left aortic valve → Aortic arch → Superior/inferior vena cavae (deoxygenated)

C corresponds with what coronary circulation

B corresponds with what coronary circulation

Middle cardiac vein

C corresponds with what coronary circulation

Posterinterventtricular artery
