The lacteals are found in
(a) spleen
(b) mammary gland
(c) salivary gland
(d) villi

Options

A. spleen
B. mammary gland
C. salivary gland
D. villi

Explanation

To solve the question regarding where lacteals are found, we can follow these steps:

### Step-by-Step Solution:

1. **Understand the Definition of Lacteals**: Lacteals are specialized lymphatic vessels that play a crucial role in the absorption of fats from the digestive system. They are important for transporting dietary lipids in the form of chylomicrons.

2. **Identify the Function of Lacteals**: Lacteals absorb fats that are broken down during digestion. These fats are not soluble in blood, so they are packaged into chylomicrons, which are then absorbed by the lacteals.

3. **Locate the Anatomical Position of Lacteals**: Lacteals are specifically located in the villi of the small intestine. The villi are small, finger-like projections that increase the surface area for absorption in the intestinal lining.

4. **Analyze the Given Options**:
- (a) Spleen: This is an organ involved in filtering blood and immune response, not fat absorption.
- (b) Mammary gland: This gland is involved in milk production, not in the absorption of fats from the digestive tract.
- (c) Salivary gland: These glands produce saliva for digestion in the mouth, not related to fat absorption.
- (d) Villi: This is the correct option as lacteals are found in the villi of the small intestine.

5. **Conclusion**: Based on the understanding of lacteals and their function, the correct answer to the question is (d) villi.

### Final Answer:
The lacteals are found in (d) villi.
