Which structure is part of the digestive tract? pancreas liver small intestine gallbladder

The correct answer is the **small intestine**.<br /><br />The digestive tract (also called the alimentary canal) is a continuous tube that runs from the mouth to the anus. Food passes through and is digested within this tract. The small intestine is a key part of this tube where a large portion of digestion and nutrient absorption occurs.<br /><br />While the pancreas, liver, and gallbladder are important accessory organs that play crucial roles in digestion (producing and storing digestive enzymes and bile), they are not *part of* the tube itself. They release their secretions into the digestive tract, but food does not pass directly through them.<br />
