Correct answer: C. Muscles in the muscularis layer
- A. Villi in the inner lining
- B. Microvilli in the epithelium
- C. Muscles in the muscularis layer
- D. Circular folds in the mucosal layer
Explanation
The correct answer ismuscles in the muscularis layerThe muscularis layer's primary function is to aid in the movement of the intestines through peristalsis. It does not have a role in increasing the surface area for absorption. On the other hand, villi, microvilli, and circular folds all serve to increase the surface area of the ileum, enhancing the absorption of nutrients.
