| vena umbilicalis sinistra | <anatomy, vein> The vein that returns the blood from the placenta to the foetus; traversing the umbilical cord, it enters the foetal body at the umbilicus and passes thence into the liver, where it is joined by the portal vein; its blood then flows by way of the ductus venosus and the inferior vena cava to the right atrium. Synonym: vena umbilicalis sinistra. (05 Mar 2000) |

| vena ventricularis inferior | Vein draining the deep white matter of the superior and lateral portions of the temporal lobe; it begins in the body of the lateral ventricle and exits from the choroid fissure of the inferior horn where it joins the basal vein. Synonym: inferior ventricular vein. (05 Mar 2000) |
| vena ventriculi lateralis lateralis | A vein draining deep portions of the temporal and parietal lobes; it runs in the lateral wall of the lateral ventricle to terminate in the superior thalamostriate vein. Synonym: vena ventriculi lateralis lateralis, lateral atrial vein, lateral vein of lateral ventricle. (05 Mar 2000) |
| vena ventriculi lateralis medialis | A vein that drains deep portions of the parietal and occipital lobes; it runs in the medial wall of the lateral ventricle to empty into the internal cerebral vein or the great cerebral vein. Synonym: vena ventriculi lateralis medialis, medial atrial vein, medial vein of lateral ventricle. (05 Mar 2000) |
| vena vermis inferior | A vein draining part of the inferior part of the cerebellum; it courses on the inferior surface of the vermis and terminates in the straight sinus. Synonym: vena vermis inferior. (05 Mar 2000) |
| vena vermis superior | A vein draining part of the superior part of the cerebellum; it runs on the superior surface of the vermis to terminate in the internal cerebral vein. Synonym: vena vermis superior. (05 Mar 2000) |
| vena vertebralis | <anatomy, vein> A vein derived from tributaries (venae comitantes) which run through the foramina in the transverse processes of the first six cervical vertebrae and form a plexus around the vertebral artery; it empties as a single trunk into the brachiocephalic veins. Synonym: vena vertebralis. (05 Mar 2000) |
| vena vertebralis accessoria | <anatomy, vein> A vein that accompanies the vertebral vein but passes through the foramen of the transverse process of the seventh cervical vertebra and opens independently into the brachiocephalic vein. Synonym: vena vertebralis accessoria. (05 Mar 2000) |
| vena vertebralis anterior | <anatomy, vein> The small vein that accompanies the ascending cervical artery; it opens below into the vertebral vein. Synonym: vena vertebralis anterior. (05 Mar 2000) |
| vena vitellina | <anatomy, vein> A vein returning blood from the yolk sac to the embryo. Synonym: vena vitellina. (05 Mar 2000) |
| groove for superior vena cava | A groove on the surface of the right lung, above the hilum, in which runs the superior vena cava. Synonym: sulcus venae cavae cranialis. (05 Mar 2000) |
| sinus of the vena cava | The portion of the cavity of the right atrium of the heart that receives the blood from the venae cavae; it is separated from the rest of the atrium by the crista terminalis. Synonym: sinus venarum cavarum. (05 Mar 2000) |
| sulcus for vena cava | A groove on the posterior surface of the liver between the caudate lobe and the right lobe which gives passage to the inferior vena cava. Synonym: sulcus venae cavae, fossa venae cavae, sulcus for vena cava. (05 Mar 2000) |
| superior vena cava | <anatomy> The major venous channel draining the thorax and head which ends in the right atrium. (19 Jan 1998) |
