The correct Answer is:
To answer the question regarding the zone of the alimentary canal where final digestion and absorption of food take place, we can follow these steps: ### Step 1: Understand the Zones of the Alimentary Canal The alimentary canal is divided into several zones based on the functions they perform during the digestion process. The main zones are: 1. **Progressive Zone**: This includes the oral cavity, pharynx, and esophagus. In this zone, food is primarily moved forward and initial digestion begins, but no final digestion occurs here. 2. **Digressive Zone**: This zone includes the stomach and small intestine. It is here that the final digestion of food takes place, along with the absorption of nutrients into the bloodstream. 3. **Agressive Zone**: This zone is associated with the oral cavity where the food is mechanically broken down (mastication) and prepared for swallowing. ### Step 2: Identify the Zone for Final Digestion and Absorption From the understanding of the zones: - The **digressive zone** is where the final digestion occurs due to the action of digestive enzymes and acids in the stomach and small intestine. - The absorption of nutrients also primarily occurs in the small intestine, where the digested food is absorbed into the bloodstream. ### Step 3: Conclusion Based on the information gathered, the correct answer to the question is that the **final digestion and absorption of food take place in the digressive zone** of the alimentary canal. ### Final Answer The zone of the alimentary canal where final digestion and absorption of food take place is the **digressive zone**. ---
