Digestion of fats takes place in the small intestine.

Fats are present as large globules in the small intestine. The liver produces bile juice, which is stored in the gall bladder and released into the small intestine. Bile breaks down large fat globules into smaller droplets — a process called emulsification. This increases the surface area for enzyme action. Then, lipase enzyme (secreted by the pancreas) acts on the emulsified fats and breaks them down into fatty acids and glycerol, which are then absorbed by the intestinal walls.

• Examiners expect three key steps: bile emulsifies fats → lipase digests them → products absorbed — each step earns a mark.
• Name the site clearly: small intestine (specifically, bile comes from liver/gall bladder; lipase from pancreas).
• The term emulsification is important — use it explicitly.
• Do not confuse emulsification (physical breakdown) with enzymatic digestion (chemical breakdown).
