Final answer:
Enterogastric reflexes are involved in the regulation of the digestive process, triggered by the entry of chyme into the duodenum, and they work by inhibiting gastric secretion and motility, and involve the enteric nervous system.
Step-by-step explanation:
Enterogastric reflexes are triggered by chyme entering the duodenum (a), which provokes inhibition of gastric secretion (b) and motility (c), and involve the enteric nervous system (d). Therefore, the correct answer is e. All of the answers provided are aspects of the enterogastric reflex.
The enterogastric reflex is a neural pathway that helps regulate the digestive process. It involves short reflexes that are mediated by the enteric nervous system, and long reflexes which are initiated by food that distends the stomach. When the duodenum fills with chyme, the reflex inhibits further gastric secretion and motility to allow the intestine to process the current contents. This is accomplished in part by closing the pyloric sphincter, thus blocking more chyme from entering the duodenum.
