Fatty acids and glycerol are first absorbed by-

Options

A. Lymph vessels
B. Blood
C. Blood capillaries
D. Hepatic portal vein

Answer

### Step-by-Step Solution:

1. **Understanding the Absorption Process**: The question asks where fatty acids and glycerol are first absorbed after digestion. It's important to understand the digestion and absorption process of fats.

2. **Digestion of Fats**: Fats are emulsified by bile salts produced by the liver. This emulsification breaks down large fat globules into smaller micelles, which are easier to absorb.

3. **Role of Micelles**: Once fats are emulsified, they form micelles that transport fatty acids and monoglycerides to the absorptive cells of the small intestine.

4. **Absorption in the Small Intestine**: In the absorptive cells, fatty acids and monoglycerides enter separately, while the micelle remains outside. Inside the cells, they recombine to form triglycerides.

5. **Formation of Chylomicrons**: After the triglycerides are formed, they are coated with proteins to create structures called chylomicrons.

6. **Entry into Lymphatic System**: Chylomicrons are too large to enter blood capillaries directly. Instead, they enter the lymphatic system through structures called lacteals, which are specialized lymph vessels.

7. **Conclusion**: Therefore, the first absorption of fatty acids and glycerol occurs in the lymph vessels (lacteals).

### Final Answer:
Fatty acids and glycerol are first absorbed by **lymph vessels**.
