The liver is an important organ that performs a variety of functions, mainly producing proteins, creating essential nutrients, producing bile that helps with digestion, filtering and removing toxins and waste products, and maintaining blood sugar levels. The gallbladder is a small organ in the digestive system that stores bile produced by the liver. Bile is what breaks down the fats in food we consume into fatty acids, which are then absorbed in the gut. Any problems with the liver and the bile duct can have serious negative effects on our health.
