Parietal cells are found in the fundic zone of the stomach.
Parietal cells in the stomach, which secrete HCl
Hydrochloric acid is secreted by the parietal cells in the stomach. These cells are located in the gastric glands lining the stomach wall. Hydrochloric acid plays a key role in the digestion of food by creating an acidic environment 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
It carries nutrients, extracted by the digestive system, to the cells; then returns waste products from the cells to the digestive system for elimination.

Stomach is where the hydrochloric acid found
specialized cells
The circulatory system picks up nutrients from the digestive system and takes them to the cells. Absorption is the process of moving the nutrients from the digestive system to the circulatory system.
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.
The chief cells in the stomach are responsible for producing digestive enzymes such as pepsinogen, which is converted into pepsin, and gastric lipase. Additionally, parietal cells secrete hydrochloric acid that helps in the breakdown of food and also creates an acidic environment to activate pepsin.
