1. **Identify the Organ Involved**: The question asks where bile is formed. The primary organ responsible for bile production is the liver.

2. **Understand the Function of the Liver**: The liver is a vital organ that performs various functions, including the production of bile. Hepatocytes, the liver cells, are specifically responsible for this process.

3. **Quantify Bile Production**: The liver produces a significant amount of bile daily, approximately 800 to 1000 ml. This highlights the liver's crucial role in digestion.

4. **Describe the Composition of Bile**: Bile is a liquid that is olive green in color and has a pH range of 7.6 to 8.6. It primarily consists of water, bile salts, bile pigments, and some ions.

5. **Function of Bile**: Bile salts are particularly important for the digestion of fats, indicating the functional significance of bile in the digestive process.
