It then travels down the neck alongside the carotid artery and internal jugular vein. Primary Innervation of the Heart One of the most critical targets of the vagus nerve is the cardiovascular system.
Intestines: Regulates absorption and the movement of food. Understanding what this nerve specifically targets reveals how deeply the mind and body are interconnected, influencing everything from heart rate to digestion.
