Bile juice is produced by the liver and stored in the gallbladder. Its main function is to aid in the digestion and absorption of fats in the small intestine. Bile contains bile salts, which help to emulsify fats, breaking them down into smaller droplets that can be more easily digested by enzymes. This process increases the surface area of the fats, allowing for better absorption of nutrients. Bile also helps to neutralize stomach acid and regulate the pH of the intestines, creating an optimal environment for digestion. Additionally, bile helps to eliminate waste and toxins from the body through the feces.

Functions of Bile Juice:
1. Digestion of Fats:
- Bile salts (cholic acid and chenodeoxycholic acid) emulsify fats in the small intestine, breaking them down into smaller droplets.
- This increases the surface area of fats, making them more accessible to enzymes (lipases) that break them down into fatty acids and glycerol.
2. Absorption of Fat-Soluble Vitamins:
- Bile salts help in the absorption of fat-soluble vitamins (A, D, E, and K) by forming micelles, which are molecular complexes that transport vitamins across the intestinal wall.
3. Neutralization of Stomach Acid:
- Bile juice is alkaline (pH 7.6-8.6) and helps to neutralize the acidic chyme (food mixed with gastric juices) entering the small intestine from the stomach.
- This creates an optimal pH for the activity of digestive enzymes in the small intestine.
4. Removal of Waste Products:
- Bile juice transports waste products, such as bilirubin (a breakdown product of hemoglobin), cholesterol, and other lipids, from the liver to the small intestine for excretion in the feces.
5. Protection against Infections:
- Bile salts have antibacterial and antifungal properties, helping to protect the small intestine from infections.
6. Regulation of Cholesterol Metabolism:
- Bile salts promote the secretion of cholesterol from the liver into the bile. Excess cholesterol is excreted in the feces, helping to regulate cholesterol levels in the body.
Additional Notes:
- Bile juice is produced by the liver and stored in the gallbladder.
- It is released into the small intestine through the common bile duct in response to the presence of fat in the chyme.
- Bile is not essential for survival, but it greatly aids in the digestion and absorption of fats.
