Abstract

The outstanding structural diversity of the placenta among mammals, i.e. horse, pig, domestic ruminants, cat. Guinea pig and human, has been studied in a comparative manner using terms of classification such as: type of placental membranes, placental shape, placental maternofetal interdigitation, layers of the placental interhemal barrier, trophoblast invasiveness and decidual cell reaction, formation of syncytiotrophoblast, maternofetal blood flow interrelationships, and placental separation at birth. These terms, originating partly from classical acquirements of knowledge and partly from recent research, are presented and new aspects discussed; thus helping towards a better understanding of the structure and function of the different placental types.
