An artery in the pulmonary circulation that carries deoxygenated blood to the lungs from the right side of the heart is called a pulmonary artery. The main pulmonary artery, also known as the pulmonary trunk from the heart, is the largest pulmonary artery, while the arterioles, which connect to the capillaries that surround the pulmonary alveoli, are the smallest. Systemic venous blood travels through the pulmonary microcirculation through the pulmonary arteries to the right side of the heart. The blood carried by the pulmonary arteries is deoxygenated because it is venous blood returning to the heart, in contrast to other organs, where arteries supply oxygenated blood. From the right side of the heart, the main pulmonary arteries split into smaller arteries that eventually become arterioles and narrow into the lungs' capillary microcirculation, where gas exchange takes place.
The pulmonary arteries begin with the pulmonary trunk, which leaves the fibrous pericardium (parietal pericardium) of the right ventricle's ventricular outflow tract, also called the infundibulum or conus arteriosus. The left superior and left posterior to the pulmonary valve is the outflow track. Below the aortic arch and in front of the left main bronchus, the pulmonary trunk divides into the right and left pulmonary arteries, respectively. The aspiratory trunk parts into the right and the left fundamental pneumonic course. Shorter than the right, the left main pulmonary artery travels to the left lung's root below the left main bronchus and behind the descending aorta. Above, the ligamentum arteriosum connects the left main pulmonary artery to the concavity of the proximal descending aorta. The right pulmonary artery enters the body in front of the right main bronchus and crosses the midline of the body below the carina of the trachea. The left primary pneumonic conduit then separates into two lobar veins, one for every curve of the left lung. It divides at the right root of the lung into interlobar artery, which supplies the right middle and inferior lobes of the lung and runs alongside bronchus intermedius, and artery, which supplies the right upper lobe of the lung and is in front of the right upper lobe bronchus. A branch connects the right and left main pulmonary arteries, or lungs, to the respective lung lobes. These conditions are referred to as lobar arteries. Segmental arteries emerge from the lobar arteries. At the posterolateral surfaces of the bronchi, segmental arteries and segmental bronchi connect. These thus branch into subsegmental pneumonic veins. Intralobular arteries are eventually formed by these.
The truncus arteriosus is a design that structures during the improvement of the heart as a replacement to the conus arteriosus. The endocardial tubes have begun to swell in the region closest to the heart by the third week of development. The swelling is referred to as the bulbus cordis, and the truncus arteriosus forms on top of it. In the end, the structure is mesodermal in origin. The heart tissues are folded as the heart develops, and the truncus arteriosus exposes what will eventually be the left and right ventricles.
