what happens to food in stomach
The inner lining of the stomach secretes hydrochloric acid, mucous, and digestive juices. The mucous secreted by the stomach protects its inner lining. The hydrochloric acid secreted by the stomach kills the bacteria that enter the stomach through food. It also makes the medium of the stomach acidic. The digestive juices secreted by the stomach take part in the process of digestion by breaking down the food into smaller substances.
