Placentation in Xenarthra. (A) Endotheliochorial placenta of the three-toed sloth, Bradypus tridactylus. The interhemal membrane comprises the enlarged maternal endothelial cells (ENDO), syncytial trophoblast (SYN TR) and the endothelium of the fetal capillary (FC). (B) Villous, hemomonochorial placenta of the nine-banded armadillo, Dasypus novemcinctus. The maternal blood space (MBS) is separated from the fetal capillary (FC) by syncytiotrophoblast (SYN TR).
