Abstract: | Blood flows were determined by electromagnetic probes placed upon the posterior vena cava (PVC), coccygeomesenteric vein (COCMV), mesenteric vein (MV), and hepatic portal vein (PV) of white Leghorn males. Blood flow in ml/min of non-fasted, unanesthetized males were as follows: (see article). Withholding food for 24 hrs decreased flow significantly only in the MV and PVC. Anesthesia decreased flow in PVC, PV and COCMV. After ligation of PVC, blood was shunted from caudal areas and renal portal circulation to COCMV and liver. Ligation of PV caused a diversion of flow to renal portal circulation and an increase in PVC flow and a reversal of direction of flow in COCMV. |
