The control of this state is complex, with contributions by the muscle and epithelium, local nerves of the enteric nervous system (ENS), the autonomic nervous system (ANS), and circulating hormones. Of these, perhaps the most important regulator of physiological gut function is the ENS (Figure 46–1).
