The stomach is one of a number of organs that make up the digestive system.
The role of the digestive system is to break down large insoluble molecules into smaller, soluble food molecules to provide the body with nutrients.
The stomach lining contains muscles which contract to physically squeeze and mix the food with the strong digestive juices that are present. Also known as "stomach churning"
