Water from the undigested food is absorbed mainly in the :

Options

A. stomach
B. food pipe
C. small intestine
D. large intestine

Answer

**Step-by-Step Solution:**

1. **Understand the Question**: The question asks where water from undigested food is absorbed in the alimentary canal.

2. **Identify the Parts of the Alimentary Canal**: The alimentary canal consists of several parts including the mouth, esophagus (food pipe), stomach, small intestine, and large intestine.

3. **Analyze Each Part for Absorption**:
- **Mouth**: Some drugs can be absorbed here, but not water from undigested food.
- **Esophagus**: This part mainly transports food to the stomach and does not absorb water.
- **Stomach**: Primarily involved in digestion, not absorption of water from undigested food.
- **Small Intestine**: This is the main site for the absorption of digested food (like glucose and amino acids), but not for undigested food.
- **Large Intestine**: This part is responsible for absorbing water and some salts from undigested food.

4. **Conclusion**: Since the large intestine is where water and some salts from undigested food are absorbed, the correct answer is the **large intestine**.

5. **Final Answer**: Water from the undigested food is absorbed mainly in the **large intestine**.
