Veins of the Heart Ventral

Ventral veins of the heart (lat. v. cordis ventrales) are a group of veins that drain blood from the anterior surface of the heart. They include the right and left cardiac veins, the anterior interventricular vein, and the smallest cardiac vein.

The right and left veins of the heart collect blood from the right and left ventricles, respectively. They open into the right atrium.

The anterior interventricular vein runs in the groove between the right and left ventricles and drains into the right atrium.

The smallest cardiac vein (vena of Tebesia) drains blood from the anterior part of the right atrium and opens directly into the right atrium.

Thus, the ventral veins of the heart provide the outflow of blood from the anterior surface of all chambers of the heart into the right atrium.
