• 6. Blood samples from the inferior vena cava, just cephalad to the outlet of the adrenal veins, had much higher concentrations of noradrenaline during cold exposure than those taken simultaneously from the jugular vein [22].
• To determine if this hypersomatostatinemia was the consequence of increased somatostatin release from the pancreas, stomach, or both, plasma SLI was measured in the pancreaticoduodenal, antral, and fundic veins and in the inferior vena cava in response to stimulation by a gastric liver test meal, followed by an intragastric HCl load [23].
• 2. Changes in plasma glucose and lactate were measured in the inferior vena cava (IVC), hepatic portal vein (HPV), hepatic vein (HV) and aorta (A) after intrajejunal administration of metformin (50 and 250 mg kg-1) without and with glucose (2 g kg-1) [24].
• Four days after surgery, blood samples were obtained simultaneously from the renal vein, aorta, and inferior vena cava for determination of oxygen content and saturation, and glucose and lactate concentrations [25].

Associations of Vena Cava, Inferior with chemical compounds
