The correct Answer is:
To solve the question "Digested lipids are absorbed from lacteals as," we will follow these steps: ### Step-by-Step Solution: 1. **Understanding Lacteals**: - Lacteals are specialized lymphatic capillaries located in the small intestine. Their primary function is to absorb dietary fats and lipids. 2. **Digestion of Lipids**: - When we consume food containing fats, these fats are initially insoluble in water. They do not get absorbed directly into the bloodstream like proteins and carbohydrates. 3. **Role of Bile Juice**: - In the small intestine, bile juice is released, which helps in the emulsification and breakdown of lipids (fats). This process converts triglycerides into smaller molecules. 4. **Breakdown Products**: - The triglycerides are broken down into monoglycerides, free fatty acids, and glycerol due to the action of bile and digestive enzymes. 5. **Formation of Micelles**: - The breakdown products (monoglycerides and fatty acids) combine with bile salts to form micelles. These micelles facilitate the transport of lipids to the intestinal mucosal cells. 6. **Absorption into Mucosal Cells**: - The micelles diffuse into the mucosal cells of the intestinal lining. Inside these cells, the fatty acids and monoglycerides are reassembled back into triglycerides. 7. **Formation of Chylomicrons**: - The newly formed triglycerides are packaged into lipoprotein particles called chylomicrons. 8. **Entry into Lacteals**: - Chylomicrons are then absorbed into the lacteals, which transport them through the lymphatic system. 9. **Final Answer**: - Therefore, digested lipids are absorbed from lacteals in the form of **triglycerides**. ### Conclusion: The correct answer to the question is **triglycerides**. ---
