Liver and Pancreas Functions · Physiology

While the liver produces bile continuously, the gallbladder's primary physiological role is to:

  1. Synthesize secondary bile acids
  2. Filter excess cholesterol from stored bile
  3. Concentrate bile by reabsorbing water and salts
  4. Activate pancreatic amylase before it reaches the gut
Show answer and explanation

Correct answer: Concentrate bile by reabsorbing water and salts

The gallbladder stores bile and increases its potency by reabsorbing sodium and water. This concentrates the bile salts and organic constituents, allowing a small volume of stored bile to handle a large amount of dietary fat.
