Solution
The correct option is C Parietal cells
The correct option is option C.
The explanation for the correct option:
- Parietal cells sometimes referred to as oxyntic cells, are stomach epithelial cells that release intrinsic factors and hydrochloric acid (HCl).
- Parietal cells secrete HCl, which helps in the conversion of ferric ions (Fe3+) to ferrous ions (Fe2+), which are absorbable.
- These cells are present in the stomach's gastric glands, which are situated in the fundus and body regions.
- Gastric acid secretion, which helps with food digestion, mineral absorption, and bacterial control, is controlled by parietal cells.
The explanation for the incorrect options:
Option A:
- All varieties of gastric glands have mucoid cells, which produce stomach mucus.
- Surface mucous cells are the protective epithelial cells that coat the outside of the stomach, including the gastric pits. For the body to fend off attacks from digestive acids and enzymes, these cells are essential. An ulcer can result from any impairment in the function of these cells.
Option B:
- The principal location for nutritional digestion and mucosal absorption is carried out by goblet cells, a kind of intestinal mucosal epithelial cell.
- Goblet cells are a specific kind of intestinal mucosal epithelial cell, and their main job is to produce and exude mucus. These mucins aid in balancing the stomach's acid production. Additionally, they aid in lubricating the epithelium to facilitate food transit.
Option D:
- The stomach contains a cell called the gastric chief cell, sometimes referred to as a zymogenic cell or peptic cell, which secretes pepsinogen and chymosin.
- When in contact with the hydrochloric acid generated by the stomach parietal cells, pepsinogen is activated into the digesting enzyme pepsin.
Final answer: Gastric cells help in the conversion of ferric ions into ferrous ions in parietal cells.
