Sulcus, running alongside the anterior interventricular artery. At the coronary sulcus, it travels with the circumflex artery to the posterior surface, where it drains into the coronary sinus.
Find the small cardiac vein as it travels alongside the right marginal artery toward the coronary sulcus. Along the coronary sulcus, it travels with the right coronary artery to the posterior surface and drains into the coronary sinus.
The anterior cardiac veins are small veins that travel a short distance along the anterior surface of the right ventricle. They drain directly into the right atrium.
Anterior view
On the posterior surface of the heart, identify two other veins that drain into the coronary sinus:
Coronary sinus
The posterior cardiac vein travels with the left marginal artery along the left ventricular wall.
The middle cardiac vein ascends along the posterior interventricular sulcus, traveling with the posterior interventricular artery.

MAKING CONNECTIONS
By observing the paths of the coronary arteries and their branches, predict the regions of the heart wall that will be supplied by the following blood vessels:
Anterior interventricular artery
Circumflex artery
Posterior interventricular artery
Right marginal artery
Left marginal artery
