The correct answer is: b. conscious neural control
Neural control of digestive tract is unconscious achieved via the autonomic nervous system.
Local nervous system of the digestive system is called the enteric or intrinsic nervous system. The major components of this nervous system are two networks or plexuses of neurons:
• The myenteric plexus – controls digestive tract motility
• The submucous plexus - regulates gastrointestinal blood flow and controls epithelial cell function.
The factor that creates the most difficulty in predicting the possible consequences of different control methods is called species interactions. An example could be competition, in which one organism fights with another for the same resources.
