Digestion and absorption in the small intestine
1. Bile produced by the liver and stored in the gall bladder is released into the duodenum
2. Bile salts break down fats into smaller fat droplets, increasing surface area for enzymes to act on
3. Pancreatic juice from the pancreas containing enzymes (amylase, protease, lipase) is secreted into the duodenum
4. Intestinal juice from the small intestine containing enzymes (maltase, protease, lipase) is secreted into the duodenum
5. Enzymes catalyse the breakdown of starch, proteins and fats
