Pulmonary trunk

The right ventricle pumps deoxygenated blood into the pulmonary trunk, which leads toward the lungs and bifurcates into the left and right pulmonary arteries.

What is Pulmonary trunk ?

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.

  • It divides into the left and right pulmonary arteries, which carry blood with relatively low oxygen content and high carbon dioxide content into the lungs.

  • The pulmonary trunk is approximately 50 mm long and 30 mm wide (most authors use 29 mm in males and 27 mm in females (axial width) as the cut-offs of normal 1,5).
