Final answer:
The liver is responsible for digestion of fats and detoxification of blood. It produces bile and stores it in the gallbladder for later use in breaking down fats.
Step-by-step explanation:
The liver is the largest internal organ in humans and it plays an important role in digestion of fats and detoxifying blood. The liver produces bile, a digestive juice that is required for the breakdown of fats in the duodenum. The liver also processes the absorbed vitamins and fatty acids and synthesizes many plasma proteins. The gallbladder is a small organ that aids the liver by storing bile and concentrating bile salts.
