Pulmonary Arteries lead from the heart to the lungs. Systemic arteries go everywhere else. Consequently, the pulmonary arteries are usually slightly smaller and thinner. There is also less of them.
The pulmonary or pulmonic valve (a semilunar valve) controls blood flow from the right ventricle to the "pulmonary trunk" that branches into the two pulmonary arteries carrying blood to the lungs.
Patent Ductus Arteriosus
Well, between the right ventricle and the pulmonary arteries is an atrioventricular valve called the PULMONARY VALVE . Between the left ventricle and the aorta is an atrioventricular valve called the AORTIC VALVE
The pulmonary artery carries blood from the heart to the lungs. The pulmonary vein carries blood to the heart from the lungs. Unlike all other veins and arteries in the body the pulmonary artery has de-oxygenated blood and the pulmonary vein has oxygenated blood.
Veins carry deoxygenated blood, arteries carry oxygenated blood, and capillaries are for gas exchange between tissues and blood. One exception to that is the pulmonary artery and pulmonary veins of the heart -- they are named backward. The pulmonary artery actually carries the deoxygenated blood from the heart to the lungs, and the pulmonary vein carries the oxygenated blood from the lungs to the heart.
Glassroth syndrome is a rare condition characterized by the presence of multiple pulmonary arteriovenous malformations (abnormal connections between arteries and veins in the lungs). This can lead to symptoms such as shortness of breath, fatigue, and an increased risk of stroke or brain abscess. Treatment typically involves embolization of the abnormal vessels to prevent complications.
The process by which blood moves between the heart and the lungs is called pulmonary circulation. Deoxygenated blood is pumped from the heart to the lungs through the pulmonary arteries, where it picks up oxygen and releases carbon dioxide. The oxygenated blood then returns to the heart via the pulmonary veins.
