The correct Answer is:
To answer the question "From the intestinal villi, fats are absorbed by," we can follow these steps: ### Step-by-Step Solution: 1. **Understanding the Structure of the Intestinal Villi**: - The intestinal wall consists of several layers, including the mucosa, which contains the villi. Villi are small, finger-like projections that increase the surface area for absorption. 2. **Digestion of Fats**: - Fats are broken down into fatty acids and glycerol in the intestinal lumen. They may also include fat-soluble vitamins (A, D, E, K). 3. **Role of Bile Salts**: - Bile salts, secreted by the liver, help emulsify fats and facilitate their absorption. The fatty acids, glycerol, and vitamins combine with bile salts to form structures known as micelles. 4. **Absorption Process**: - Micelles are absorbed by the enterocytes (cells of the villi). Once inside these cells, the fatty acids and glycerol are reassembled into larger fat molecules and coated with proteins to form chylomicrons. 5. **Transport of Chylomicrons**: - Chylomicrons are then transported into the lymphatic system through specialized lymph capillaries known as lacteals, which are present in each villus. 6. **Final Answer**: - Therefore, from the intestinal villi, fats are absorbed by the lacteals (lymph capillaries). ### Conclusion: The correct answer to the question is that fats are absorbed by **lymph capillaries** (lacteals) from the intestinal villi. ---
