The aorta supplies oxygenated blood from the heart's pumping chamber to the rest of the body. And Pulmonary artery carries deoxygenated or unaerated blood from the heart to the lungs.
In the lungs, the blood becomes purified and oxygenated again. It then travels back to the left side of the heart to be distributed throughout the body. The right ventricle must first pump the blood to force it through the pulmonary valve and into the pulmonary trunk, which is the only outlet from the right ventricle. From here, the blood travels through each of the pulmonary arteries to reach the corresponding lungs The pulmonary trunk is a major vessel of the human heart that originates from the right ventricle. It branches into the right and left pulmonary arteries, which lead to the lungs. Each of these vessels has elastic walls similar to those of the aorta, though somewhat thinner, and they are considered to be arteries even though the blood they carry is not oxygenated. The trunk itself is relatively short and wide. It then travels back to the left side of the heart to be distributed throughout the body. The right ventricle must first pump the blood to force it through the pulmonary valve and into the pulmonary trunk, which is the only outlet Pulmonary artery is one of the two vessels branching from the pulmonary trunk is an integral part of the whole heart anatomy and is the vessel that transports de-oxygenated blood to the lungs coming from the right ventricles. The right pulmonary artery is longer of the two arteries. The pulmonary artery connects the lungs and the right ventricle of heart and is divided into left pulmonary artery and right pulmonary artery. The deoxygenated blood collected from the body is sent back to the heart’s right ventricle. The aorta supplies oxygenated blood from the heart's pumping chamber to the rest of the body. Pulmonary artery carries deoxygenated or unaerated blood from the heart to the lungs.Like all arteries, the pulmonary artery carries blood away from the heart. Diffen › Science › Biology › Anatomy. The aorta and the pulmonary artery are the two most important arteries in the human body. The aorta is the biggest artery and channels oxygenated blood to the rest of the body. The pulmonary artery carries deoxygenated blood to the lungs for purification. In the human heart, the pulmonary trunk (pulmonary artery or main pulmonary artery) begins at the base of the right ventricle. It is short and wide—approximately 5 centimetres (2.0 in) in length and 3 centimetres (1.2 in) in diameter. The pulmonary artery carries deoxygenated blood from the right ventricle to the lungs. The blood here passes through capillaries adjacent to alveoli and becomes oxygenated as part of the process of respiration. In contrast to the pulmonary arteries, the bronchial arteries supply nutrition to the lungs themselves The pulmonary trunk is a blood vessel which divides to form the right and left pulmonary arteries. At the base of this trunk is a pulmonary semilunar valve that is made up of three leaflets or cusps.  Pulmonary trunk: A vessel that arises from the right ventricle of the heart, extends upward, and divides into the right and left pulmonary arteries that convey unaerated blood to the lungs.  The pulmonary artery carries deoxygenated blood from the heart to the lungs. It is one of the only arteries (other than the umbilical arteries in the fetus) that carries deoxygenated blood. The pulmonary artery carries deoxygenated blood from the right ventricle to the lungs. The blood here passes through capillaries adjacent to alveoli and becomes oxygenated as part of the process of respiration. In contrast to the pulmonary arteries, the bronchial arteries supply nutrition to the lungs themselves
