Describe the function of both bronchial arteries. are these vessels components of pulmonary circulation or systemic circulation?

Answer and explain:

Bronchial arteries are provenient of thoracic aorta. Their origin is in systemic circulation and their function is provide oxygen blood to big vessels, visceral pleura and walls and glands of bronquios. Also, bronchial arteries are encharged of humidify the air to reduce it loses by evaporation in alveolar surface.

Bronchial arteries are components of systemic circulation.  

Bronchial arteries give the nutritional circulation to the non-respiratory structures in the lungs. The left bronchial arteries are usually 2, they directly emerge from the thoracic aorta, while the right bronchial artery emerges from the third intercostal artery or from the left superior bronchial arteries. That the bronchial arteries emerge from aorta explains how they made a part of systemic circulation.

Before these arteries penetrate the lungs, they also give some branches to pericardium, lymphatic ganglia’s, esophagi and bronchioles. This circulation is characterized for having a high pressure but a low flux. The pressure that these arteries manage has no significant differences whit the aortic pressure.
