Maximum digestion of food take place in-

Options

A. Stomach
B. Jejunum
C. Colon
D. Duodenum

Answer

**Step-by-Step Solution:**

1. **Understanding the Question**: The question asks where the maximum digestion of food occurs in the human digestive system.

2. **Evaluating the Options**:
- **Option 1: Stomach**: The stomach primarily functions to macerate food (mechanical breakdown) and acts as a reservoir for food before it moves to the small intestine. While some digestion occurs here, it is not the site of maximum digestion.
- **Option 2: Jejunum**: The jejunum is a part of the small intestine and is involved in the absorption of nutrients. However, it is not the primary site for maximum digestion; that role is fulfilled by another part of the small intestine.
- **Option 3: Colon**: The colon, or large intestine, is mainly responsible for the absorption of water, ions, and vitamins. There is no significant digestion that occurs here, so this option is incorrect.
- **Option 4: Duodenum**: The duodenum is the first part of the small intestine and is where the majority of digestion occurs. It is responsible for the breakdown of carbohydrates, fats, and proteins, and also plays a crucial role in nutrient absorption.

3. **Conclusion**: After evaluating all the options, the correct answer is that maximum digestion of food takes place in the **duodenum**.

**Final Answer**: Maximum digestion of food takes place in the **duodenum**.
