Gastric juices are produced in the gastric pits and secreted into the StomachThey contain pepsin(a type of protease) an enzyme that breaks down proteins, acid which makes the pepsin break down food faster and mucus that coats the walls of your stomach to stop the enzymes breaking them down as well.Read more: Discuss:What_is_the_function_of_the_gastric_juice_in_the_stomach
The stomach has gastric pits lined with mucous-secreting cells and gastric glands that secrete hydrochloric acid and enzymes for digestion. In contrast, the small intestine has finger-like projections called villi that increase surface area for absorption, with intestinal glands containing cells responsible for nutrient absorption.
The rugae gradually smooth out as the stomach fills, permitting stomach distension. A cross section of the stomach lining reveals that in between the rugae are gastric pits, which are the openings of the gastric glands.

The stomach
The inner wall of the stomach of the fetal pig is lined with gastric mucosa, which contains gastric pits leading to gastric glands. These gastric glands secrete enzymes and mucus that aid in digestion. The lining also has rugae, which are folds that allow for expansion of the stomach.

Gastric pits in the stomach produce gastric juice, which contains hydrochloric acid, digestive enzymes like pepsin, and mucus. These components work together to help break down food and aid in the digestion process.

Gastric juice is secreted from gastric glands, which are located in narrow tube like structures called gastric pits. Gastric juice contains hydrochloric acid, pepsinogenand mucus in a healthy adult. Hydrochloric acid is secreted by parietal cells, pepsinogen is secreted by gastric chief cells and mucus is secreted by mucus neck cells. Source: Wikipedia
