Intestinal villi are supplied with -

Options

A. Only blood capillaries
B. Only lacteals
C. Lacteals and valves
D. Blood capillaries and lacteals

Answer

### Step-by-Step Solution:

1. **Understanding Intestinal Villi**:
- Intestinal villi are small, finger-like projections located in the lining of the small intestine. They increase the surface area for absorption of nutrients.

2. **Cell Types Present**:
- The inner lining of the intestinal villi is made up of specialized cells known as enterocytes, which are a type of columnar epithelium. These cells play a crucial role in nutrient absorption.

3. **Blood Supply to Villi**:
- Each villus contains a network of blood vessels, specifically capillaries. These blood vessels are responsible for the absorption of water-soluble nutrients, which are then transported into the bloodstream.

4. **Lacteals in Villi**:
- In addition to blood vessels, each villus also contains a lymphatic vessel known as a lacteal. Lacteals are important for the absorption of fats and fat-soluble substances, which are transported through the lymphatic system.

5. **Conclusion**:
- Therefore, intestinal villi are supplied with both blood capillaries and lacteals, allowing for the absorption of different types of nutrients.

### Final Answer:
Intestinal villi are supplied with both blood capillaries and lacteals.
