The hepatic portal vein receives nutrient-rich blood from the small intestine. What are the two primary functions of this vein, as described in the text?

  • A: To produce bile salts for fat emulsification and to store excess glucose as glycogen.
  • B: To facilitate the direct absorption of chylomicrons into the bloodstream and regulate blood pressure.
  • C: To regulate the distribution of nutrients to the rest of the body and remove toxic substances before broader circulation.
  • D: To initiate enzymatic digestion of proteins and reabsorb water and ions.

Explanation

The text states: 'This arrangement serves two major functions. First, it allows the liver to regulate the distribution of nutrients to the rest of the body... Second, the arrangement allows the liver to remove toxic substances before they can circulate broadly.'
