Parietal cells are found in the fundic zone of the stomach. Their main function is to produce hydrochloric acid, which assists in the chemical breakdown of food.

Parietal cells
Parietal cell or proximal gastric vagotomy leaves the trunk intact, but severs the branches that go to different parts of the stomach.
Osteoclast (most likely from my point of view)
The stomach cell that secretes hydrochloric acid is called a parietal cell. These cells are responsible for producing the hydrochloric acid that helps in the digestion of food in the stomach.
Hydrochloric acid is secreted by the parietal cells in the stomach. They are responsible for producing the acidic environment necessary for digestion and killing bacteria in the stomach.
Chief cells in the stomach work with parietal cells to produce gastric acid. Chief cells secrete pepsinogen, which is activated by the acid produced by parietal cells to form pepsin, an enzyme that helps break down proteins. Together, parietal and chief cells contribute to the digestive process in the stomach.
Parietal cells
The parietal cell has several unique organelles, including mitochondria for producing energy, secretory vesicles for storing and releasing digestive enzymes, and tubulovesicles for transporting and recycling cellular materials. Additionally, parietal cells contain an extensive network of tubulovesicles called canaliculi, which are involved in the secretion of hydrochloric acid into the stomach.
Chief cells of the stomach (gastric glands in stomach have chief cells)
Parietal cells in the stomach secrete hydrochloric acid (HCl) to help digest food and kill bacteria. They also produce intrinsic factor, which is necessary for the absorption of vitamin B12 in the small intestine. Additionally, parietal cells regulate the acidity of the stomach by secreting bicarbonate ions to help maintain the pH balance.
