Fats are absorbed by
(a) arteries
(b) veins
(c) capillaries
(d) lacteals

Options

A. arteries
B. veins
C. capillaries
D. lacteals

Explanation

To solve the question "Fats are absorbed by," we will analyze the options provided and understand the process of fat absorption in the human body.

### Step-by-Step Solution:

1. **Understanding Fat Digestion**: Fats are initially broken down in the digestive system by enzymes such as lipase into smaller components, primarily fatty acids and glycerol.

**Hint**: Remember that fats need to be broken down into smaller molecules before absorption.

2. **Formation of Micelles**: The fatty acids and glycerol are insoluble in water, which means they cannot be directly absorbed into the bloodstream. Instead, they form small droplets called micelles that help transport these molecules to the intestinal mucosa.

**Hint**: Think about how fats, being insoluble, require a special mechanism to be absorbed.

3. **Reformation into Chylomicrons**: Once at the intestinal mucosa, the fatty acids and glycerol are reassembled into larger fat globules, which are then coated with proteins. These structures are known as chylomicrons.

**Hint**: Chylomicrons are crucial for the transport of fats; they are formed after the fats are processed in the intestines.

4. **Absorption via Lacteals**: Chylomicrons are absorbed into specialized lymphatic vessels called lacteals, which are located in the villi of the small intestine. This is where the fats enter the lymphatic system.

**Hint**: Consider where in the body the absorption of fats primarily takes place.

5. **Release into the Bloodstream**: After being absorbed by the lacteals, the chylomicrons eventually enter the bloodstream, allowing the body to utilize the absorbed fats.

**Hint**: Remember that lacteals are part of the lymphatic system that connects to the bloodstream.

### Conclusion:
Based on the above steps and understanding of fat absorption, the correct answer to the question "Fats are absorbed by" is:

**(d) lacteals**
