right heart: (vena cavae, coronary sinus) → right atrium (fossa ovalis) → tricuspid valve → right ventricle → pulmonic valve
→ (pulmonary artery and pulmonary circulation)
left heart: (pulmonary veins) → left atrium → mitral valve → left ventricle → aortic valve
→ (aorta, aortic sinus and systemic circulation)
