Assemble a working digestive tract! Place the various organs in the correct place so that you can digest food and score as many points as possible. Have you put your digestive tract together properly? If so, the ingested food will be broken down and assimilated so you can gain nutrients. Use them to progress to higher levels of the game and improve your system. The more points you score, the more new organs you can access in order to improve the digestive tract you have created! This game helps you understand how the organs of the digestive tract work. You can also learn about the nutrients in food. Some parts of the game are not realistic from a scientific point of view. They have been adapted for better gameplay. In real life, the salivary gland is only associated with the mouth. Saliva does not break down all fragments of food into nutrients and we do not have more than one stomach, liver or pancreas!
