small cardiac vein การใช้

It receives blood from the great cardiac vein ( receiving the left atrium and both ventricles ), the posterior cardiac vein ( draining the back of the left ventricle ), the middle cardiac vein ( draining the bottom of the left and right ventricles ), and small cardiac veins.
It is formed by the folding of the serous layer over the remnant of the lower part of the left superior vena cava ( duct of Cuvier ), which becomes obliterated during fetal life, and remains as a fibrous band stretching from the highest left intercostal vein to the left atrium, where it is continuous with a small cardiac vein, the vein of the left atrium ( oblique vein of Marshall ), which opens into the coronary sinus.
