In human anatomy, the bronchial arteries supply the lungs with oxygenated blood, and nutrition.

[1] The left bronchial arteries (superior and inferior) usually arise directly from the thoracic aorta.

They anastomose with the branches of the pulmonary arteries, and together, they supply the visceral pleura of the lung in the process.

[1] The bronchial arteries are typically enlarged and tortuous in chronic pulmonary thromboembolic hypertension.

[9] The bronchial arteries can maintain a supply of oxygenated blood to lung tissue.
