1. Metabolism: The liver plays a key role in metabolizing nutrients, drugs, and toxins. It helps convert carbohydrates, proteins, and fats into energy and essential molecules needed for various bodily functions.
2. Detoxification: The liver filters and detoxifies harmful substances, such as alcohol, drugs, and environmental toxins, from the blood. It also helps break down and eliminate waste products produced by the body.
3. Storage: The liver stores essential nutrients, such as vitamins, minerals, and glycogen, for later use. It also stores blood and regulates blood volume to maintain proper circulation.
4. Synthesis: The liver produces important proteins, such as albumin, clotting factors, and cholesterol, that are necessary for various bodily functions, including blood clotting and immune system function.
5. Bile production: The liver produces bile, a digestive fluid that helps break down fats and aids in the absorption of fat-soluble vitamins. Bile is stored in the gallbladder and released into the small intestine during digestion.
6. Regulation of blood sugar levels: The liver helps regulate blood sugar levels by storing and releasing glucose as needed. It also plays a role in maintaining a constant supply of glucose to the brain and other organs during periods of fasting or physical activity.
