[2025-09-29T12:32:17.610729] [PI reasoning] **Clarifying chief cells' location**

I need to answer a question about the anatomy of gastric glands. Chief cells, also called zymogenic cells, are found in the base of the gastric glands, particularly in the fundus and body of the stomach. The histology shows distinct zones: pit, isthmus, neck, and base. Chief cells are specifically located in the fundus. So, the answer is likely "A Fundus." To support this, I might need citations from textbooks or articles. A quick search could help validate this!
