The liver performs several important functions in the body, including:

1. Metabolism: The liver plays a key role in metabolizing nutrients, drugs, and toxins. It helps convert carbohydrates, fats, and proteins into energy and stores essential nutrients for later use.

2. Detoxification: The liver filters and detoxifies harmful substances, such as alcohol, drugs, and environmental toxins, from the blood.

3. Production of bile: The liver produces bile, a digestive fluid that helps break down fats and aids in the absorption of fat-soluble vitamins.

4. Storage: The liver stores essential nutrients, such as vitamins and minerals, as well as glycogen, a form of glucose that can be used for energy when needed.

5. Regulation of blood sugar levels: The liver helps regulate blood sugar levels by storing and releasing glucose as needed.

6. Production of proteins: The liver produces proteins that are essential for blood clotting, immune function, and maintaining fluid balance in the body.

7. Regulation of cholesterol levels: The liver helps regulate cholesterol levels by producing and excreting cholesterol as needed.

8. Synthesis of hormones: The liver plays a role in the synthesis of hormones, such as insulin and estrogen, that are important for various bodily functions.

Metabolic Functions:

- Glycogenesis and Glycogenolysis: Stores and releases glucose as needed to maintain blood sugar levels.
- Gluconeogenesis: Produces glucose from non-carbohydrate sources (e.g., proteins, fats) during fasting or low-carbohydrate states.
- Lipolysis and Lipogenesis: Breaks down fats into fatty acids and synthesizes new fats for storage or energy production.
- Ketone Body Production: Converts fatty acids into ketone bodies for energy use by the brain and other tissues during starvation or low-carbohydrate states.
- Protein Synthesis: Produces plasma proteins (e.g., albumin, clotting factors) and other specialized proteins.
- Bile Synthesis: Produces bile, which helps digest and absorb fats.

Detoxification Functions:

- Drug Metabolism: Breaks down and removes drugs and their metabolites from the body.
- Alcohol Metabolism: Converts alcohol into harmless substances.
- Ammonia Detoxification: Converts toxic ammonia into less harmful urea.

Homeostatic Functions:

- Blood Volume Regulation: Stores and releases blood as needed to maintain blood pressure.
- Splenic Contraction: Contracts to release red blood cells into circulation during times of blood loss or stress.
- Thermoregulation: Releases heat or cools the body as necessary to maintain core body temperature.

Storage Functions:

- Glycogen Storage: Stores glucose in the form of glycogen for quick energy release.
- Vitamin Storage: Stores vitamins A, D, B12, and K.
- Iron Storage: Stores iron in the form of ferritin.

Other Functions:

- Immunological Function: Contains immune cells that help filter toxins and pathogens from the blood.
- Blood Coagulation: Produces clotting factors necessary for blood coagulation.
- Endocrine Function: Produces hormones such as insulin-like growth factor (IGF-1).
- Reservoir of Blood: Contains approximately 13% of the body's blood volume.
