Quizplus · Accepted Answer

The digestive tract is a long tube that starts at the mouth and ends at the anus. The contents of this tube, including food, water, and waste products, are technically outside of the body until they are absorbed into the bloodstream through the walls of the intestines. Therefore, the digestive tract is considered to be part of the external environment of the body.
