what does the pulmonary plexus do
An autonomic nerve plexus extending from the cardiac plexus into the lungs along the right and left pulmonary arteries. Parasympathetic axons come from the vagus nerves, and sympathetic axons from the sympathetic trunk. Axons from the pulmonary plexus follow the bronchi and the bronchial vessels and provide the autonomic innervation inside the lungs.
