Mark the following statements as true or false. If a statement is false, correct it to make a true statement.
a. Motility of the alimentary canal is regulated by the enteric nervous system, the parasympathetic nervous system, and hormones.
b. The esophageal and pharyngeal phases of swallowing are mediated by the swallowing reflex of the brainstem and the enteric nervous system.
c. Smooth muscle of the stomach contracts when food enters from the esophagus.
d. Control of gastric emptying into the duodenum is important to allow the chyme to be neutralized and diluted by pancreatic secretions.
e. During eating, the small intestine exhibits motion in the migrating motor complex pattern.
