The arteries that nourish the lungs are the bronchial arteries.
The bronchial arteries are the nutrient vessels of the lung tissue, belonging to the system of body circulation, supplying the respiratory bronchioles and all levels of bronchial tubes above them, and anastomosing with the terminal capillaries of the pulmonary arteries. The bronchial arteries originate from the arch of the aorta or the thoracic aorta in the majority of the population and lie flat against the anterior wall of the thoracic aorta, at the level of the 4th-6th thoracic vertebra.
The bronchial arteries are relatively small, with individual variability in number and origin, usually two on the left and two on the right, and most emanate from the beginning of the thoracic aorta and enter the lungs with the bronchi.
The bronchial arteries are very important blood vessels for supplying nutrients to the lung tissues, exchanging metabolic wastes and nutrients through their blood supply, and carrying out the normal exchange of carbon dioxide and oxygen.
If you experience any discomfort in the lungs, please seek medical attention to avoid any delay.
