pulmonary artery









































a pulmonary artery is an artery in the pulmonary circulation that carries deoxygenated blood from the right side of the heart to the lungs. the largest pulmonary artery is the "main pulmonary artery" or "pulmonary trunk" from the heart, and the smallest ones are the arterioles, which lead to the capillaries that surround the pulmonary alveoli.

in order of blood flow, the pulmonary arteries start as the pulmonary trunk or main pulmonary artery. the main pulmonary artery begins at the base of the right ventricle. it is short and wide—approximately in length and in diameter.

the main pulmonary artery splits into the right and the left main pulmonary artery. the left main pulmonary artery is shorter and somewhat smaller than the right, passes horizontally in front of the descending aorta and left bronchus to the root of the left lung. above, the left main pulmonary artery is connected to the concavity of the proximal descending aorta by the ligamentum arteriosum. it then divides into two lobar arteries, one for each lobe of the left lung. the right main pulmonary artery follows a longer and more horizontal course as it crosses the mediastinum. it passes underneath the aortic arch, behind the ascending aorta, and in front of the descending aorta. it courses posterior to the superior vena cava and in front of the right bronchus. upon reaching the hilum of the right lung the right main pulmonary artery divides into two branches:
