Pulmonary Artery Function

The primary pulmonary artery function is to carry blood from the right ventricle of the heart to the lungs. The pulmonary artery connects the right ventricle of the heart to the lungs and it has been divided into left and right pulmonary artery. The deoxygenated blood from the body is resent in the right ventricle of the heart. This blood is pumped by counteraction in the heart muscles lining the wall of the right ventricle.

Thus the deoxygenated blood passes through the pulmonary artery into the lungs. The pulmonary artery carried the deoxygenated blood from the right ventricle into the lungs were replenished with oxygen and then returned to the left ventricle of the heart. When an individual is suffering from pulmonary hypertension there is high blood pressure in the pulmonary arteries. It may be caused due to various factors or an obstruction that retards the pulmonary artery function. Therefore as a result of this condition the right ventricle becomes weak and there is an increased risk of right ventricular failure.

The pulmonary artery function is absent in the case of a developing fetus. When a fetus is growing and developing inside the others womb, he may not requires oxygen from lungs as deriving it from the mother’s umbilical cord. This is the only time when there is no pulmonary artery function.
