Which two types of gastric cells produce gastric juice?

In gastric glands, the two cell types that actually produce the digestive components of gastric juice are parietal cells and chief cells. Parietal cells secrete hydrochloric acid (HCl) and intrinsic factor, creating the acidic environment needed for protein digestion and for activating pepsinogen. Chief cells secrete pepsinogen, the inactive zymogen that is activated to pepsin by the acidic milieu. Together, HCl and pepsinogen constitute gastric juice, enabling protein digestion in the stomach. Other cells, like mucus-secreting cells, G cells, and D cells, contribute to protection and regulation but do not themselves produce gastric juice components.
