The principle organ in humans involved in the absorption of nutrients like glucose ,fructose, fatty acids , glycerol and amino acids is

Options

A. Stomach
B. Small intestine
C. Mouth
D. large intestine

Answer

To solve the question regarding the principal organ in humans involved in the absorption of nutrients like glucose, fructose, fatty acids, glycerol, and amino acids, we can follow these steps:

### Step 1: Identify the Options
The question provides four options:
1. Stomach
2. Small intestine
3. Mouth
4. Large intestine

### Step 2: Analyze Each Option
- **Stomach**: The stomach is primarily involved in the digestion of food. It breaks down larger food molecules into smaller ones through mechanical and chemical processes. However, it is not the main site for nutrient absorption.

- **Small Intestine**: The small intestine is the major site for nutrient absorption in the human body. It has specialized structures (villi and microvilli) that increase the surface area for absorption of nutrients such as glucose, fructose, fatty acids, glycerol, and amino acids.

- **Mouth**: The mouth is responsible for the intake of food and the initial mechanical digestion through chewing. It does not play a significant role in nutrient absorption.

- **Large Intestine**: The large intestine primarily functions in the absorption of water and electrolytes. It is also involved in the formation and excretion of fecal matter, but it is not the main site for nutrient absorption.

### Step 3: Conclusion
Based on the analysis, the organ that is primarily responsible for the absorption of nutrients like glucose, fructose, fatty acids, glycerol, and amino acids is the **small intestine**.

### Final Answer
The principal organ in humans involved in the absorption of nutrients like glucose, fructose, fatty acids, glycerol, and amino acids is the **small intestine**.
