The pulmonary trunk emerges from the right ventricle and bifurcates into right and left pulmonary arteries beneath the aortic arch. The right pulmonary artery passes behind the ascending aorta to the right lung. The left pulmonary artery passes anterior to the descending aorta to the left lung.

Type Vessel
Body System Cardiovascular
Body Region Heart Region
Parent Structure artery
Latin Name Arteria pulmonalis
FMA ID 66326

Function

Carries deoxygenated blood from the right ventricle to the lungs for gas exchange. The only artery in the postnatal body that carries deoxygenated blood.

Clinical Significance

Pulmonary embolism is obstruction of the pulmonary artery or its branches by blood clots, potentially fatal. Pulmonary hypertension increases right ventricular workload. Pulmonary artery catheterization (Swan-Ganz) monitors cardiac function.
