There are multiple definitions:

1. pulmonary vein(English)

   • apart from differences in cellular electrophysiology, the PV area also shows salient features in gross anatomy and fiber geometry. The area between the PVs shows a strong preferential superior-inferior fiber orientation on the epicardial side, corresponding with the main propagation direction during sinus rhythm

5. portal vein(English)

   • the main vessel of the portal venous system (PVS), which drains the blood from the gastrointestinal tract, gallbladder, pancreas, and spleen to the liver. There are several variants affecting the PV, and quite a number of congenital and acquired pathologies

6. parasitophorous vacuole(English)

   • a unique replicative niche for apicomplexan parasites, including Toxoplasma gondii. Derived from host plasma membrane, the vacuole is rendered nonfusogenic with the host endolysosomal system. Toxoplasma secretes numerous proteins to modify the forming vacuole, enable nutrient uptake, and set up mechanisms of host subversion
