Final answer:
The correct response to the question is vomiting, which is a protective reflux initiated when the stomach lining is significantly irritated, involving nervous system coordination.
Step-by-step explanation:
When the stomach lining is significantly irritated, sensory signals are sent to the brainstem, and motor signals return to various structures to cause vomiting. This response is a protective reflex that helps to expel harmful substances from the stomach. In the context of gastric control, there are three overlapping phases: the cephalic phase, the gastric phase, and the intestinal phase, each requiring many enzymes and under neural control. The stomach muscle contractions, neural signals that urge elimination, and various digestive processes are all coordinated by the nervous system, especially in reaction to sensory inputs like stomach distension, which can trigger receptors in the stomach wall to initiate reflexive actions.
