Digestive System Stomach
null
The stomach where food is sent to be converted from bolus bits to chyme. The gastric juices of the stomach break down food stuff into a semisolid mixture called chyme. The stomach muscles run in several different directions and are layered in longitudinal, circular, and oblique angles. This allows the stomach to move food in various directions without it getting stuck in any one particular area. The folds in the stomach are called rugae which appear when the stomach is empty. The stomach is broke down into three basic areas they are fundus, body, and pylorus.
The fundus is part of the stpmach which lies above the gastroespoghageal opening. The plyorus is the bottom section or part of the stomach that joins the small intestine with the stomach. The muscle the hold food in the stomach while it’s being further broken down into chyme is called the pylorus sphincter.
The gastric juices are very acidic and break down most of the carbs and proteins of the body. The fats and fiber require a more mechanical and bile to break them down. Next I will go into the intestines of the body and talk about the role that they play in the digestive system.
