Dec 13, 2018 · Right Pulmonary Artery (RPA): directs blood to the right lung. Extending from the pulmonary trunk, it dips under the aortic arch and behind the superior vena cava to the right lung. The RPA branches into smaller vessels within the lung. Left Pulmonary Artery (LPA): directs blood to the left lung. It is shorter than the RPA and is a direct ...

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. In addition, you can take the following actions to support your heart health: Avoid smoking, vaping or using any tobacco products. Your healthcare provider can offer resources to help you quit. Eat a heart-healthy diet with plenty of fresh fruits and vegetables. Get at least 150 minutes (2.5 hours) of cardiovascular physical activity every week. Keep a weight that’s healthy for you. Manage conditions like diabetes, high blood pressure and high cholesterol. Advertisement
When should I talk to a doctor?
Call your healthcare provider if you experience: Bluish lips or skin color. Chest pain, tightness or discomfort. Coughing up blood. Dizziness or fainting. Irregular heartbeat (arrhythmia). Nausea and vomiting. Rapid pulse. Shortness of breath. Swollen ankles, feet or abdomen (edema). A note from Cleveland Clinic Your pulmonary arteries carry oxygen-poor blood from your heart to your lungs. They’re a vital part of your circulatory system. But because you can’t see them, it can be easy to forget they’re working hard every day. That’s why it’s helpful to learn your pulmonary artery anatomy along with the lifestyle changes you can make to support your heart and blood vessels. Learning how your body works can help make the invisible become visible. Ask your healthcare provider what you can do to keep your pulmonary arteries and circulatory system healthy.

Jun 7, 2024 · Specifically, this member was referring to a condition known as a pulmonary embolism. In a pulmonary embolism, a blood clot from another part of the body breaks off and travels through the body’s network of veins up to the heart and then to the lungs. Blood clots can get stuck in a vein and cause a blockage in blood flow.
Oct 30, 2023 · The pulmonary trunk carries the deoxygenated blood into the lungs via the right and left pulmonary arteries. At the level of pulmonary capillaries, gaseous exchange occurs between blood in the capillaries and the alveoli of the lungs resulting in the removal of carbon dioxide and the oxygenation of the blood. Oxygen-rich blood is then returned ...

The blood flow through the pulmonary circulation is as follows; the right ventricle, pulmonary artery, alveoli, pulmonary vein, left atria. This is essential for gas exchange at the lung. It is important to note that bronchial circulation is not the same as pulmonary circulation, as it is still part of the systemic circulation.

How do pulmonary arteries carry deoxygenated blood?
The pulmonary artery carries deoxygenated blood into the lungs from the heart, where it branches and eventually becomes the capillary network composed of pulmonary capillaries. These pulmonary capillaries create the respiratory membrane with the alveoli (Figure 8.4.2). As the blood is pumped through this capillary network, gas exchange occurs.
