The liver is the body’s largest organ. It is vital and serves many important functions, including producing chemicals necessary for digestion (e.g., bile, enzymes and cholesterol), breaking down toxic substances and removing waste products from the body. All the nutrients and toxic substances that enter the body eventually reach the liver, where they are broken down into byproducts that the body can use or eliminate.

The biliary system is made up of the organs and ducts that produce and transport bile. It consists of the gallbladder and the bile ducts. Bile is produced in the liver and stored in the gallbladder. Its two main functions are assisting in the digestion and absorption of fat and eliminating waste products from the body.

Many disorders may affect the liver or biliary system, including bile duct disorders, cirrhosis of the liver, gallstones and hepatitis. Many people have their gallbladders removed and still have biliary function. The liver can withstand great damage over time and even regenerate its tissue. However, extreme damage that kills liver cells eventually affects the organ’s ability to function properly, resulting in liver failure. Liver failure can require organ transplantation. If an organ is not available, liver failure can cause death.

Tips for maintaining a healthy liver and biliary system include avoiding alcohol or drinking it in moderation, eating a well-balanced diet and practicing safe sex by using a condom.
