Fat digestion is facillitated by

Options

A. Bile juice
B. Pancreatic juice
C. Gastric juice
D. Intestinal juice.

Answer

**Step-by-Step Solution:**

1. **Understanding Fat Digestion**: Fat digestion is a complex process that involves breaking down large fat globules into smaller molecules that can be absorbed by the body.

2. **Identifying the Role of Bile Juice**: Bile juice, produced by the liver and stored in the gallbladder, plays a crucial role in fat digestion. It is released into the small intestine (specifically the duodenum) when chyme (partially digested food) enters.

3. **Function of Bile Salts**: Bile contains bile salts, which are essential for emulsifying fats. Emulsification is the process of breaking down large fat globules into smaller droplets, increasing the surface area for enzymes to act upon.

4. **Alkaline Nature of Bile**: Bile is alkaline in nature, which helps neutralize the acidic chyme coming from the stomach. This creates an optimal environment for the action of digestive enzymes.

5. **Interaction with Pancreatic Juice**: While pancreatic juice also contributes to fat digestion by providing enzymes like lipase, it is the bile that primarily facilitates the emulsification of fats, making them more accessible for enzymatic breakdown.

6. **Conclusion**: Therefore, the correct answer to the question "Fat digestion is facilitated by" is **bile juice**.
