Pulmonary Trunk 3D

  • Description                                                                  
    • * Is the solitary arterial output from the right ventricle, transporting deoxygenated blood to the lungs for oxygenation.
    • * Extends upward from the conus arteriosus of the right ventricle of the heart.
    • * Passes superiorly and posteriorly from the front of the ascending aorta and bifurcates into the right and left pulmonary arteries at the level of sternal angle.

 

  • Right Pulmonary Artery:
    • * Is longer than the left pulmonary artery and carries deoxygenated blood to the right lung.
    • * Courses perpendicularly away from the pulmonary trunk and left pulmonary artery, between the superior vena cava and the right main bronchus.
    • * Divides into upper lobar artery and descending interlobar artery.

 

  • Left Pulmonary Artery:
    • * Is shorter and narrower than the right pulmonary artery.
    • * Carries deoxygenated blood to the left lung and arches over the left primary bronchus.
    • * Is connected to the arch of the aorta by the ligamentum arteriosum.
    • * Divides into 2 lobar branches and subsequently into segmental and sub segmental branches.
