The single right bronchial artery usually arises from one of the following:

Each bronchial artery also has a branch that supplies the esophagus.

However, they only carry 13% of the blood flow of the bronchial arteries.

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

The bronchial arteries supply blood to the bronchi and connective tissue of the lungs.

The left bronchial arteries (superior & inferior) usually arise directly from the thoracic aorta.

The bronchial veins are counterparts to the bronchial arteries.

In contrast to the pulmonary arteries, the bronchial arteries supply nutrition to the lungs themselves.

Although there is much variation, there are usually two bronchial arteries that run to the left lung, and one to the right lung.

Aneurysms of the bronchial artery may mimic aortic aneurysms.

These arteries branch from the pulmonary and bronchial arteries, and run together through the center of the segment.

Angiography of bronchial arteries can be performed to locate the bleeding, and it can often be embolized.

The tracheal branches of the inferior thyroid artery are distributed on the trachea, and anastomose below with the bronchial arteries.

Note that much of the blood supplied by the bronchial arteries is returned via the pulmonary veins rather than the bronchial veins.

It is easy to confuse the bronchial arteries with the pulmonary arteries, because they both supply the lungs with blood, but there are important differences:

Bronchial artery (rami bronchiales partis thoracicae aortae) (Arteriae bronchiales)

Even when the pulmonary aneurysm is present, the actual bronchial bleeding may be from the bronchial artery, rather than from the pulmonary artery.

In bronchial artery embolization for treatment of massive hemoptysis, one of the most serious complications is inadvertent occlusion of the artery of Adamkiewicz.

Anatomical shunting occurs when too much of the blood supplying the lung tissues via the bronchial arteries is being returned via the pulmonary veins without undergoing gas exchange.

Small physiological, or "normal", shunts are seen due to the return of bronchial artery blood and coronary blood through the Thebesian veins, which is deoxygenated, to the left side of the heart.

Making this task more difficult is the anatomy of the lung and pathophysiology of chronic thromboembolic pulmonary hypertension (CTEPH); lungs also get blood from the bronchial arteries are often enlarged.

The thoracic descending aorta gives rise to the intercostal and subcostal arteries, as well as to the superior and inferior left bronchial arteries and variable branches to the esophagus, mediastinum, and pericardium.

The root is formed by the bronchus, the pulmonary artery, the pulmonary veins, the bronchial arteries and veins, the pulmonary plexuses of nerves, lymphatic vessels, bronchial lymph glands, and areolar tissue, all of which are enclosed by a reflection of the pleura.
