Quizplus · Accepted Answer

Digestive activities are regulated and controlled by local factors, neural mechanisms, and hormonal mechanisms. Local factors include the presence of food, stretching of the digestive tract wall, and pH changes. Neural mechanisms include central nervous system reflexes and local enteric nervous system reflexes. Hormonal mechanisms include the release of gastrointestinal hormones such as gastrin, secretin, and cholecystokinin. Therefore, the best choice is E, which includes all three major mechanisms.
