These lymph vessels ultimately release the absorbed substances into the (f)_____

Answer

**Step-by-Step Text Solution:**

1. **Identify the Nature of Fatty Acids and Glycerol:**
- Fatty acids and glycerol are hydrophobic substances, meaning they do not mix well with water and cannot be absorbed directly into the bloodstream.

2. **Formation of Small Droplets:**
- To facilitate their absorption, fatty acids and glycerol are first incorporated into small droplets known as **micelles**. These micelles help transport the hydrophobic substances through the aqueous environment of the intestine.

3. **Movement into the Intestinal Mucosa:**
- The micelles then move into the intestinal **mucosa**, which is the innermost layer of the intestinal wall where absorption takes place.

4. **Reformation into Chylomicrons:**
- Once inside the intestinal mucosa, fatty acids and glycerol are re-formed into very small protein-coated fat globules called **chylomicrons**. This transformation is crucial for their transport in the lymphatic system.

5. **Transport into Lymph Vessels:**
- Chylomicrons are then transported into the **lymph vessels** located in the villi of the intestine. Villi are tiny, finger-like projections that increase the surface area for absorption.

6. **Release into the Blood:**
- Finally, these lymph vessels release the absorbed substances, including chylomicrons, into the **blood**. This allows the fatty acids and glycerol to enter the bloodstream and be distributed throughout the body.

**Completed Paragraph:**
Fatty acids and glycerol being (a) **hydrophobic**, cannot be absorbed into the blood. They are first incorporated into small droplets called (b) **micelles** which move into the intestinal (c) **mucosa**. They are re-formed into very small protein-coated fat globules called the (d) **chylomicrons** which are transported into the (e) **lymph vessels** in the villi. These lymph vessels ultimately release the absorbed substances into the (f) **blood**.
