Which organ is NOT part of the digestive system pathway?

The trachea is not part of the digestive system pathway; rather, it is a structure of the respiratory system. Its primary function is to allow air to pass from the throat to the lungs. The digestive system, on the other hand, includes organs that are involved in the processing of food. The esophagus, stomach, and large intestine are integral components of this system, facilitating the ingestion, breakdown, and absorption of nutrients from food, followed by the elimination of waste. Understanding the distinct roles of the trachea versus the digestive organs clarifies why it does not belong to the list of digestive system components.
