3. What is bile and why is it important for digestion?Bile is a yellow‑green liquid made by the liver that helps break down fats into tiny droplets so the body can absorb them.
4. How does bile help the body get vitamins from food?Bile mixes with fat‑soluble vitamins A, D, E, and K to make tiny micelles that can cross the intestine wall and enter the bloodstream.

Hepatocytes: The main functional cells of the liver responsible for producing bile and performing metabolic functions.
Bilirubin: A yellow pigment produced from the breakdown of heme, excreted in bile, and contributing to its color.
Amphipathic: Having both hydrophilic (water-loving) and hydrophobic (water-repelling) parts, a property of bile salts crucial for emulsification.
Mixed Micelles: Aggregates formed by bile salts, cholesterol, and fatty acids that facilitate fat absorption in the small intestine.
