How are the digestive problems of heartburn and gastric ulcers particularly related to the stomach? Describe the function of the stomach including the roles that pepsin and hydrochloric acid play. How are the digestive problems of heartburn and gastric ulcers particularly related to the stomach? • The functions of the stomach are to continue the breakdown of food, to store food, to mix together the food and gastric juices, and to control the rate at which food enters the small intestine. Pepsin and hydrochlordic are a part of the gastric juices secreted by the stomach. The digestive problems of heartburn and a gastric ulcer are particularly related to the gastric juices from the stomach. For example, a cause of heartburn is the backflow of stomach acids into the esophagus. A gastric ulcer develops when something damages the stomach’s protective lining, allowing the stomach acids to “eat away” to it.
