Verified step by step guidance1
Understand the definition of accessory digestive organs: These are organs that assist in the digestive process but are not part of the main digestive tract.
Identify the main digestive tract organs: These include the mouth, esophagus, stomach, small intestine, and large intestine.
Recognize the role of the gallbladder, liver, and pancreas: These organs produce or store substances that aid in digestion, such as bile and enzymes, but food does not pass through them.
Consider the function of the stomach: It is a primary organ of the digestive tract where food is mixed and broken down by stomach acids and enzymes.
Conclude that the stomach is not an accessory organ because it is directly involved in the digestion process as part of the main digestive tract.
