Explanation:
Detailed explanation-1: -The vagus nerve is responsible for the regulation of internal organ functions, such as digestion, heart rate, and respiratory rate, as well as vasomotor activity, and certain reflex actions, such as coughing, sneezing, swallowing, and vomiting (17).
Detailed explanation-2: -Neuroanatomy, Cranial Nerve 10 (Vagus Nerve)-StatPearls-NCBI Bookshelf.
Detailed explanation-3: -The vagus nerve stimulates the intestines to push food (or “chime”) along the intestinal tract (“peristalsis”). Proper peristalsis mixes and shifts the chime, allowing proper nutrient absorption. Poor peristalsis can result in gastroparesis, constipation, bloating and discomfort.
