In the digestive tract, which term means closer to the mouth?

Proximal describes something that is closer to the mouth along the digestive tract. As you move from mouth toward the anus, you pass from proximal regions to distal regions. For example, the portion of the esophagus near the mouth is proximal, while portions nearer the rectum are distal. Anterior and posterior tell front/back orientation and don’t indicate distance along the canal, so they don’t describe closeness to the mouth.
