The left lung lies lateral to the left ventricle, aorta, left subclavian artery, left brachiocephalic vein, trachea, esophagus, and left phrenic and vagus nerves. Cadaveric lung impressions demonstrate the differences in the mediastinal relations. On the left lung, there is a deep impression from the left ventricle which forms the cardiac notch.

Your pulmonary arteries carry blood from your heart to your lungs. They’re the only arteries in your body that carry oxygen-poor (deoxygenated) blood. Your main pulmonary artery (pulmonary trunk) leaves your right ventricle at your pulmonary valve. It soon splits into your right and left pulmonary arteries, which carry blood to each of your lungs.

What does the pulmonary artery do?
Your pulmonary arteries carry oxygen-poor blood from your heart to your lungs. This is a vital function. Your blood needs to reach your lungs to gain oxygen and get rid of waste products like carbon dioxide. This blood then returns to your heart, and your heart pumps it out to the rest of your body.
Where are the pulmonary arteries located?
Your pulmonary arteries are located in your chest cavity. Your main pulmonary artery (pulmonary trunk) connects to your right ventricle at your pulmonary valve at the front of the heart. From there, it leaves your heart and travels upward along the left side of your ascending aorta. Beneath your aortic arch, your main pulmonary artery splits into the right pulmonary artery and left pulmonary artery. These arteries then travel to each of your lungs.
What common conditions and disorders affect the pulmonary arteries?
The most common problems that affect the pulmonary arteries are congenital heart defects. These issues are present at birth. Congenital heart conditions that may affect your pulmonary arteries include: Double outlet right ventricle. Patent ductus arteriosus. Pulmonary atresia. Pulmonary artery stenosis. Pulmonary valve stenosis. Tetralogy of Fallot. Transposition of the great arteries. Truncus arteriosus. Conditions that can affect adults’ pulmonary arteries include: Pulmonary embolism. Pulmonary hypertension. Pulmonary valve regurgitation. Heart Failure. Cirrhosis. Sickle Cell Anemia. Scleroderma. Obstructive sleep apnea. Obesity. Sarcoidosis. Chronic Obstructive Pulmonary Disease. Interstitial Lung Disease. Lupus.
How can I protect my heart and pulmonary arteries?
Many conditions that affect your pulmonary arteries are present at birth. While you can’t prevent congenital diseases, there are other diseases that you should manage well to prevent the development of pulmonary hypertension. These include: Chronic obstructive pulmonary disease (COPD). Obstructive sleep apnea. Heart failure.

The left pulmonary artery accompanies the left main bronchus to reach the hilum of the left lung. Here, it bifurcates into superior and inferior lobar arteries. The distal branches of the left pulmonary artery accompany the segmental bronchi, usually in a posterolateral position. The branches of the left pulmonary artery can be extremely ...
The left lung lies lateral to the left ventricle, aorta, left subclavian artery, left brachiocephalic vein, trachea, esophagus, and left phrenic and vagus nerves. Function The lungs are involved in respiration, which is the process of gas exchange between the atmospheric air and the blood.
The left pulmonary artery has an anomalous origin from the posterior aspect of the right pulmonary artery and passes between the trachea and the esophagus (Fig 1), leading to compression of the trachea and the right main bronchus. 2 Most commonly, these patients present with stridor, wheeze, and recurrent respiratory tract infections.
