The '''pulmonary arteries''' carry [[blood]] from the [[heart]] to the [[lungs]]. They are the only [[artery|arteries]] (other than [[Umbilical artery|umbilical arteries]] in the fetus) that carry deoxygenated blood.
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 cm (2 inches) in length and 3 cm (1.2 inches) in diameter. It then branches into two pulmonary arteries (left and right), which deliver deoxygenated blood to the corresponding [[lung]].
== Role in disease ==
[[Pulmonary hypertension]] occurs alone and as a consequence of a number of [[pulmonology|lung diseases]]. It can be a consequence of [[heart disease]] ([[Eisenmenger's syndrome]]) but equally a cause (right-ventricular [[heart failure]]); it also occurs as a consequence of [[pulmonary embolism]] and [[scleroderma]]. It is characterised by reduced exercise tolerance. Severe forms, generally, have a dismal prognosis.
