Quizplus · Accepted Answer

All of the above choices can regulate the activities of the digestive system. Hormones, such as gastrin and secretin, can stimulate or inhibit digestive processes. Parasympathetic neurons promote digestion, while sympathetic neurons inhibit it. The presence of food or chyme in the digestive tract can also trigger neural and hormonal responses to regulate digestive functions. Intrinsic nerve plexuses within the wall of the digestive tract can coordinate local reflexes to regulate intestinal contractions and secretions.
