Why pulmonary artery is an artery

Nutrients and oxygen are delivered to every cell in your body through a circulatory system. The heart pumps oxygenated blood to your cells through arteries. It pumps oxygen-depleted blood away from your cells through veins. If you have chronic health conditions, your blood oxygen level may fall outside of the normal range.

The purpose of the pulmonary circulation is to transfer oxygen and carbon dioxide between the blood in the body and the air that's inhaled and exhaled in the lungs.

The specific role of the pulmonary arteries is to carry blood that's low in oxygen and high in carbon dioxide waste to the pulmonary capillaries of the lungs, where this exchange takes place.

When the blood is enriched with oxygen and cleared of carbon dioxide waste, it flows back through your pulmonary veins to your heart's right ventricle. From there, the blood is pumped to the left ventricle and finally dispersed through the aorta to the arteries that carry the oxygen-rich blood throughout the body.

There are two main conditions that affect the pulmonary arteries in adults— pulmonary embolus PE and pulmonary arterial hypertension. Pulmonary arterial hypertension is a rare disease that develops over time. A PE is a blood clot in an artery of the lungs, and it is a medical emergency. A PE is a condition in which a blood clot lodges in the pulmonary artery, blocking blood flow to the lungs.

Symptoms include:. A PE can occur when a blood clot forms in a vein such as in the legs and travels through the heart, eventually becoming lodged in a pulmonary artery. Risk factors include blood clotting disorders, cancer , and prolonged physical immobility. A pulmonary embolism is a life-threatening medical emergency that must be treated with blood thinners or an interventional procedure.

Pulmonary arterial hypertension is a rare type of pulmonary hypertension characterized by narrowing, stiffening, and thickening of the arteries in and around the lungs.

It can cause fatigue, shortness of breath, hemoptysis coughing up blood , and leg swelling. Pulmonary arterial hypertension can develop without a known reason, and risk factors include scleroderma or other connective tissue diseases, toxin exposure, and liver cirrhosis. The condition is progressive and may result in severe heart failure and disability due to intolerance of physical activity.

The pulmonary arteries carry blood from your heart to your lungs. These vessels are part of the pulmonary circulation, and they are affected by and have an effect on other blood vessels in this system. Congenital deformities of the heart can be associated with variations in the pulmonary arteries, and these issues may require surgical repair during childhood.
