Which of the following is NOT part of the digestive tract?

The pancreas is indeed not part of the digestive tract. It is classified as an accessory organ in the digestive system. While the pancreas plays an essential role in digestion by producing digestive enzymes and hormones such as insulin, it does not form part of the actual pathway through which food travels during digestion. The digestive tract comprises a continuous tube that runs from the mouth to the anus, including structures like the oesophagus, stomach, and large intestine. Understanding the distinction between the digestive tract and accessory digestive organs is crucial for comprehending how the digestive system functions as a whole.
