Gastrointestinal secretion is a significant and important matter in animal life.
Gastrointestinal secretions are under the control of the sympathetic ganglia located in the walls of the digestive tract. They rule secretion. One nerve plexus is a complement of the other. As secretion without motion is of little avail, and motion without secretion is equally futile, peristaltic motion is necessary to sweep onward the food to be attacked by fresh glandular secretion and to eliminate and drain the system from the debris of food. The remnants of the gastrointestinal feast must be removed by peristaltic movements.
