The Stomach

  • 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"
  • Food is digested within the stomach for several hours
    The-Stomach
