Fig. 5. Cross-section through tip of primary lung rudiment of a chick of 24 somites

Cross-section (10 micron) through tip of primary lung rudiment of a chick of 24 somites, 48 hours' incubation; carmine stain, series E. The right two-thirds of the mass of angioblasts has formed the tip of the left valve of the sinus. The common pulmonary vein is now established, opening into the sinus to the left of the valve. Angioblasts can be seen spreading over the ventral surface of the gut. This is the earliest stage in which the common vein is complete.
