Bronchial veins are thereby part of the bronchial circulation, carrying waste products away from the cells that constitute the lungs. The bronchial veins are counterparts to the bronchial arteries. However, they only carry ~13% of the blood flow of the bronchial arteries. [1] The remaining blood is returned to the heart via the pulmonary veins. [1]
The bronchial circulation is the part of the systemic circulation that supplies nutrients and oxygen to the cells that constitute the lungs, as well as carrying waste products away from them. It is complementary to the pulmonary circulation that brings deoxygenated blood to the lungs and carries oxygenated blood away from them in order to ...
[1] [2] These arteries branch from the pulmonary and bronchial arteries, and run together through the center of the segment. Veins and lymphatic vessels drain along the edges of the segment. The segments are separated from each other by layers of connective tissue that forms them into discrete anatomical and functional units.

The pulmonary arteries carry deoxygenated blood to the lungs, where carbon dioxide is released and oxygen is picked up during respiration. [3] Arteries are further divided into very fine capillaries which are extremely thin-walled. [4] The pulmonary veins return oxygenated blood to the left atrium of the heart. [3]
A list of veins in the human body: Veins of the heart. Coronary sinus. Great cardiac vein; Oblique vein of left atrium; Middle cardiac vein; Small cardiac vein; Pulmonary veins; Superior vena cava. Brachiocephalic vein. Inferior thyroid vein; Inferior laryngeal vein; Pericardial veins; Pericardiophrenic veins; Bronchial veins; Vertebral vein ...
Oxygen-poor blood enters the right side of the heart through two large veins. Oxygen-rich blood from the lungs enters through the pulmonary veins on the left side of the heart into the aorta and then reaches the rest of the body. The capillaries are responsible for allowing the blood to receive oxygen through tiny air sacs in the lungs.
The accessory hemiazygos vein varies inversely in size with the left superior intercostal vein.. It usually receives the posterior intercostal veins from the 4th, 5th, 6th, 7th, and 8th intercostal spaces between the left superior intercostal vein and highest tributary of the hemiazygos vein; [3] the left bronchial vein sometimes opens into it.
