Ghrelin is produced by epithelial cells lining which region of the stomach?

Explanation:
Ghrelin-producing cells are endocrine cells located in the fundic mucosa of the stomach, specifically in the fundic glands of the fundus (with some presence in the upper body). These ghrelin-secreting cells release the hunger-stimulating hormone into the bloodstream, which helps regulate meal initiation and energy balance. That regional localization explains why the fundus is the correct answer. The antrum mainly contains gastrin-secreting cells, while the pylorus and cardia have different roles and do not serve as the primary source of ghrelin.
