Verified step by step guidance1
Understand the role of the vagus nerve (CN X) in the parasympathetic nervous system, which primarily innervates organs involved in rest and digest functions.
Identify the organs listed in the problem: spleen, adrenal glands, heart, and kidneys.
Recall that the vagus nerve is responsible for innervating the heart, lungs, and digestive tract, among other organs.
Consider the function of each organ: the heart is directly involved in cardiovascular regulation, which is a key area influenced by the vagus nerve.
Conclude that the heart is the organ innervated by the vagus nerve, as it plays a significant role in autonomic regulation through parasympathetic input.
