Placentas are described morphologically according to the distribution of villi on the chorionic surface and the degree of separation between maternal and fetal blood. Placentas’ endocrine roles are: 1) pregnancy maintenance; 2) stimulation of the maternal mammary gland; and 3) promotion of fetal growth....
