Final answer:
The correct order of components in digestive tracing is stratified squamous epithelium, lingual papilla, gastric rugae, villi, and Peyer's patches. This sequence mirrors the actual path that food takes through the digestive system, from ingestion to the small intestine.
Step-by-step explanation:
The correct order for DIGESTIVE tracing is:
- Stratified squamous epithelium
- Lingual papilla
- Gastric rugae
- Villi
- Peyer's patches
This order traces the path of food as it moves through the digestive system. The stratified squamous epithelium lines the mouth and esophagus, protecting underlying tissues. As food passes through the mouth, it comes into contact with the lingual papilla, which contains taste buds. The food then enters the stomach where the gastric rugae help to grind and churn it. Afterward, it moves into the small intestine where it encounters the villi, which are responsible for nutrient absorption. Finally, Peyer's patches, which are part of the gut-associated lymphoid tissue (GALT), provide immune surveillance within the ileum of the small intestine.
