Answer :
The pulmonary artery leaves the right ventricle of the heart to take oxygen-poor, dark-red blood into the pulmonary circulation.
Deoxygenated blood is delivered to the lungs by the pulmonary artery from the right ventricle. Here, as part of the respiratory process, the blood flows via capillaries close to the alveoli and is oxygenated.
What is pulmonary circulation?
All vertebrates have a part of the circulatory system called pulmonary circulation. Deoxygenated blood that has been returned to the body enters the circuit in the right atrium of the heart, where the right ventricle pumps it to the lungs.
In order to supply the rest of the body with oxygenated blood and to remove carbon dioxide from circulation, it primarily functions by exchanging gases across the alveolar membrane.
