The pulmonary artery is a vital component in the re-oxygenation (putting oxygen back into blood) of the human body. It transports de-oxygenated blood from the heart to the lungs, where oxygen is "re-infused" into the blood.
The pulmonary artery is an important component of our respiratory system. Its main function is to carry oxygen-depleted (or deoxygenated) blood from our heart (right ventricle) to the lungs. The pulmonary artery originates at the base of the right ventricle and has a diameter of 3 cm and length of 5 cm. It then divides into the right and left pulmonary artery, each of which supplies deoxygenated blood to the corresponding lung. It is one of the rare arteries in a human body that carries deoxygenated blood; the umbilical artery carries deoxygenated blood in a fetus. The blood gets oxygenated at the lungs and is supplied back to the heart (from where it is supplied to the rest of the body).
Pulmonary hypertension is a disorder related to increased pressure in the pulmonary artery and can cause heart failure.
Sorry correction to my answer above it should be deoxygenated blood to be re-oxygenated
The pulmonary artery PULLS deoxyenated blood to the lungs, from the heart. There are two pulmonary arteries, a small left and a LARGE right.
Arteries pump blood away from the heart carrying oxygenated blood to tissues throughout the body for the purpose of cellular respiration to provide energy. Specific arteries are named based on where they carry the blood to. The pulmonary artery carries oxygenated blood to the lungs to allow cellular respiration to take place in ling tissue so the lungs have energy for proper functioning.
