Explanation:

- The human body has several structures lined by layers of tissues for protection and function.

- Stomach: The stomach wall has four layers, but they're specialized for stomach functions.

- Throat: Layers here are adapted for respiration and food passage, not identical to the typical four.

- Gastrointestinal: This is right. The gastrointestinal tract, from the esophagus to rectum, has the mucosa, submucosa, muscularis, and adventitia/serosa.

- Nasal: Nasal walls have different epithelial layers for breathing and filtering.
