The gallbladder stores and concentrates bile.
Explanation
- The gallbladder is a small organ located under the liver whose main function is to store bile produced by the liver and concentrate it by removing water and electrolytes, making the bile up to 3 to 10 times more concentrated.
- This concentrated bile is released into the small intestine when needed, primarily to aid in the digestion and absorption of fats by emulsifying large fat globules into smaller droplets.
- Bile contains water, bile salts, cholesterol, bile pigments (such as bilirubin), and other components that help with fat digestion and waste elimination.
Thus, the blank is filled with "bile " as the substance stored and concentrated by the gallbladder.
