What produces bile, crucial for fat digestion?

Bile is produced by the liver, which plays a vital role in fat digestion and absorption. The liver synthesizes bile acids from cholesterol, and these bile acids are essential for emulsifying fats in the small intestine, thus allowing for better digestion and absorption of dietary fats.

Once bile is produced, it is stored and concentrated in the gallbladder until needed during digestion. However, the production itself occurs in the liver. The small intestine is where bile acts, but it does not produce bile. The pancreas produces digestive enzymes and bicarbonate, which assist with digestion but are separate from the bile production process.
