| venae perforantes | The veins that accompany the perforating arteries from the profunda femoris artery; they drain blood from the vastus lateralis and hamstring muscles and terminate in the profunda femoris vein. Synonym: venae perforantes. (05 Mar 2000) |

| venae pericardiacae | Several small veins from the pericardium emptying into the brachiocephalic veins or superior vena cava. Synonym: venae pericardiacae. (05 Mar 2000) |
| venae pericardiacophrenicae | The veins accompanying the pericardiacophrenic artery and emptying into the brachiocephalic veins or superior vena cava. Synonym: venae pericardiacophrenicae. (05 Mar 2000) |
| venae peroneae | Venae comsitantes of the peroneal artery; they join the posterior tibial veins to enter the popliteal vein. Synonym: venae peroneae, venae fibulares, fibular veins. (05 Mar 2000) |
| venae pharyngeae | Several veins from the pharyngeal venous plexus emptying into the internal jugular vein. Synonym: venae pharyngeae. (05 Mar 2000) |
| venae phrenicae superiores | Small veins that drain the upper surface of the diaphragm; they are tributaries of the azygos and hemiazygos veins. Synonym: venae phrenicae superiores. (05 Mar 2000) |
| venae pontis | Several veins running transversely on the pons to join the petrosal vein. Synonym: venae pontis, veins of pons. (05 Mar 2000) |
| venae prefrontales | The superficial veins draining the prefrontal cerebral cortex and emptying into the superior sagittal sinus. Synonym: prefrontal veins. (05 Mar 2000) |
| venae profundae clitoridis | The veins that pass from the dorsum of the clitoris to join the vesical plexus. Synonym: venae profundae clitoridis. (05 Mar 2000) |
| venae pudendae externae | These correspond to the arteries of the same name; they empty into the great saphenous vein or directly into the femoral vein, and receive the superficial dorsal vein of the penis (clitoris) and the anterior scrotal (or labial) veins. Synonym: venae pudendae externae. (05 Mar 2000) |
| venae pulmonales | The veins that return the oxygenated blood from the lungs to the left atrium of the heart. (12 Dec 1998) |
| venae radiales | Venae comitantes of the raidal artery continuing from those of the radial aspect of the deep palmar arch, draining into the venae comitantes of the brachial artery in the cubital fossa. Synonym: venae radiales. (05 Mar 2000) |
| venae rectae | The ascending limbs of the vasa rectae in the renal medulla. (05 Mar 2000) |
| venae rectales inferiores | Veins that pass to the internal pudendal vein from the inferior rectal venous plexus around the anal canal. Synonym: venae rectales inferiores. (05 Mar 2000) |
| venae rectales mediae | Several veins that pass from the rectal venous plexus (in which they anastomose with the superior rectal veins) to the internal iliac vein, which ultimately drains into the inferior vena cava. Since the superior rectal veins ultimately drain into the portal vein, the middle retal veins participate in a portocaval anastomosis, and the rectal venous plexus is subject to varicosities during portal hypertension. Synonym: venae rectales mediae. (05 Mar 2000) |
