Heart Anatomy
Coronary Veins Page 4
- Coronary veins(a) return blood from cardiac muscle and empty into the coronary sinus(b).
- The coronary sinus returns blood to the right atrium(c)
The Cardiac Cycle Page 5
- In atrial systole(a), the atriums contract pushing blood into the ventricles.
- In ventricular systole(b) the ventricles contract, ejecting blood into the aorta and pulmonary vein.
- In ventricular diastole, the ventricle relax
