1
Understand the role of accessory organs in the digestive system. Accessory organs are those that aid in digestion but are not part of the digestive tract itself.
Identify the primary function of each organ listed: the liver, pancreas, and gallbladder are all accessory organs that produce or store substances to aid digestion.
Recognize that the stomach is part of the digestive tract itself, where the initial breakdown of food occurs through mechanical and chemical processes.
Differentiate between the digestive tract and accessory organs: the digestive tract includes organs through which food passes, while accessory organs assist in digestion without being part of the tract.
Conclude that the stomach is not an accessory organ because it is directly involved in the digestion process as part of the digestive tract.
