| venae cordis minimae | Numerous small valveless venous channels that open directly into the chambers of the heart from the capillary bed in the cardiac wall, enabling a form of collateral circulation unique to the heart. Synonym: smallest cardiac veins, thebesian veins. (05 Mar 2000) |
| ventriculus cordis | One of the two lower chambers of the heart. Synonym: ventriculus cordis. (05 Mar 2000) |
