The Japanese Journal of Animal Reproduction
The maternal vascular architecture of the dog girdle placenta from 30 to 63 (full term) days of pregnancy was investigated on corrosion casts by means of scanning electron microscopy. Each zone in the zonary girdle of the dog placenta was supplied by the radial arteries which were emitted from the arcuate arteries.
