Quizplus · Accepted Answer

The beginning of the digestive tract is the mouth, and the end of the gastrointestinal tract is the anus. Therefore, the correct answer is D. Option A and C are incorrect because the small intestine and stomach are not at the beginning or end of the gastrointestinal tract, but in the middle. Option B is incorrect because the pancreas is not part of the digestive tract, but it does secrete enzymes into the small intestine to aid in digestion.
