What is the important function of bile-

Options

A. 1)For digestion by emulsification of fats
B. 2)Elimination of excretory products
C. 3)For digestion by enzymes
D. 4)Coordination of digestive activities

Answer

### Step-by-Step Solution:

1. **Understanding Bile**: Bile is a digestive fluid produced by the liver and stored in the gallbladder. It plays a crucial role in the digestion of fats.

2. **Composition of Bile**: Bile is composed of several components, including:
- Cholesterol
- Bile salts
- Bilirubin
- Bicarbonate ions

3. **Function of Bile**: The primary function of bile is to aid in the digestion of fats. This is achieved through a process known as emulsification.

4. **Emulsification Process**: Emulsification is the process by which bile salts break down large fat globules into smaller droplets. This increases the surface area for enzymes to act upon, facilitating better digestion of fats.

5. **Location of Action**: The emulsification of fats occurs in the small intestine, where bile is released to assist in the digestion process.

6. **Evaluating Options**: Given the options:
- Option 1: Digestion by emulsification of fats (Correct)
- Option 2: Elimination of expiratory products (Incorrect)
- Option 3: Digestion by enzymes (Incorrect)
- Option 4: Coordination of digestive activities (Incorrect)

7. **Conclusion**: The important function of bile is best described by option 1, which states that it aids in digestion by emulsification of fats.
