The microscopic picture in the pulmonary artery could not be told from that in a syphilitic aorta.
Continue to lay open the ventricle towards the pulmonary artery until the semilunar valves come into view.
The distribution of the pulmonary artery is considered in connexion with the anatomy of the lungs (see Respiratory System).
At the extremity of the divisions of the aorta, as well as the pulmonary artery, are found capillary vessels.
In the first part of the aorta, pulmonary artery and arteries of the retina there is no muscular coat.

These veins start from very minute vessels the continuation of the capillaries of the pulmonary artery.
