The small cardiac vein
(right coronary vein
or vena cardiaca parva
) runs in the coronary sulcus
between the right atrium
and ventricle, and opens into the right extremity of the coronary sinus
It receives blood from the back of the right atrium and ventricle; the right marginal vein ascends along the right margin of the heart and joins it in the coronary sulcus, or opens directly into the right atrium.
