What two structure produce substances involved in the digestion of fat?

The two structures that produce substances involved in the digestion of fat are the pancreas and the liver. The pancreas secretes digestive enzymes, including lipases, which break down fats into fatty acids and glycerol. The liver produces bile, stored in the gallbladder, which emulsifies fats, making them easier for lipases to act upon during digestion. Together, these substances facilitate the efficient breakdown and absorption of dietary fats in the small intestine.
