Explanation:
Detailed explanation-1: -The mucosal barrier protects the stomach from self-digestion. It includes a thick coating of bicarbonate-rich mucus; the mucus is physically protective, and bicarbonate neutralizes gastric acid.
Detailed explanation-2: -The surface mucus cells (foveolar cells) are mucus-producing cells that primarily line the gastric mucosa. The secreted mucus acts as a barrier to the corrosive nature of the gastric acid. The rest of the specialized cells are found deep within the gastric glands (i.e., gastric pits).
