The upper five or six anterior intercostal arteries are branches of the internal thoracic artery (anterior intercostal branches of internal thoracic artery).The internal thoracic artery then divides into its two terminal branches, one of which - the musculophrenic artery - proceeds to issue anterior intercostal arteries to the remaining 6th, 7th, and 9th intercostal spaces; these diminish in ...

The bronchial arteries supply blood to the bronchi and connective tissue of the lungs. They travel with and branch with the bronchi , ending about at the level of the respiratory bronchioles . They anastomose with the branches of the pulmonary arteries , and together, they supply the visceral pleura of the lung in the process.
