title: Study of the diameter and number of the pulmonary veins orifices.
abstract: The present study was made in the anatomy laboratory on 100 heart specimens. It was studied the morphological parameters about diameter and number of the atrial orifices of the pulmonary veins. The number of the orifices and their diameter depends on the lungs weight. Generally (70% of the cases) the orifices number is four and rarely three or five. An increased number of orifices are more frequently in the right side and a decreased number especially in the left side. The orifices diameter is much larger at the male's veins than the female's ones, and much larger in the right than the left side and also much larger at the superiors than the inferior veins.
