Where is gastric juice stored in the stomach?

Gastric juice is not stored in a specific location within the stomach; instead, it is secreted by the gastric glands in the stomach lining as needed. The stomach has different regions, including the fundus, body, and antrum, where these glands release gastric juice containing hydrochloric acid, enzymes, and mucus. When food enters the stomach, the gastric juice is mixed with it to aid in digestion.
