| Anatomical terminology |
A heart valve normally allows blood to flow in only one direction through the heart.
The four valves are commonly represented in a mammalian heart that determines the pathway of blood flow through the heart.
A heart valve opens or closes incumbent on differential blood pressure on each side.[1][2][3]

- (venae cavae, coronary sinus) → right atrium (atrial appendage, fossa ovalis, limbus of fossa ovalis, crista terminalis, valve of inferior vena cava, valve of coronary sinus) → tricuspid valve → right ventricle (infundibulum, moderator band/septomarginal trabecula, crista supraventricularis), → pulmonary valve → (pulmonary artery and pulmonary circulation)

| Left heart |
- (pulmonary veins) → left atrium (atrial appendage) → mitral valve → left ventricle → aortic valve (aortic sinus) → (aorta and systemic circulation)
