Final answer:
The Portal vein would not typically exhibit continuous flow in the listed veins.
Step-by-step explanation:
Among the listed veins, the vein that would not typically exhibit continuous flow is the Portal vein. The hepatic portal system is responsible for carrying blood from the digestive organs and the spleen to the liver for processing. The portal vein itself receives blood from the superior mesenteric vein, splenic veins, and other tributaries. This blood flow is not continuous because it is regulated by the liver and is dependent on the needs of the body.
