Small Cardiac Vein
The structure indicated is the
small cardiac vein. The
coronary sinus lies posteriorly on the heart in the
coronary sulcus and receives
four cardiac veins:
- Great cardiac vein
- Middle cardiac vein
- Small cardiac vein
- Posterior cardiac veins
The coronary sinus returns
deoxygenated blood to the right atrium of the heart, together with the superior and inferior
vena cavae. The small cardiac vein lies in the coronary sulcus between the right atrium and the right ventricle. Learn more about the
blood supply to the heart in this tutorial.
