Fig. 8. Origin of the Pulmonary Vessels in the 36 somite chick

A 36-somite chick of 60 hours' incubation, injected with ink and dissected by the paraffin method. Only the right half of the vascular tree is shown. This stage is but slightly older than that in figure 7. The, pulmonary arch is now complete but still retains a capillary appearance. The pulmonary artery can be recognized in the cephalic portion of the plexus. The right lobar tributary of the common vein is formed and is connected with its corresponding artery on the dorsal surface of the lung-bud. The cranial tributary of the common vein is plainly seen. The wall of the sinus venosus has been removed to show the opening of the common pulmonary vein into the sinus.
