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. It then branches into two pulmonary arteries (left and right), which deliver deoxygenated blood to the corresponding lung.
