Abstract
The chorioallantoic placenta is the principal organ of exchange processes between mother and fetus in most higher mammals. Three fetal components, namely trophoblast, connective tissue, and capillary wall, build the histological barrier in hemochorial placentae. Species specific variations of the trophoblast are well known, examples of which are hemomonochorial (man, guinea pig), hemodichorial (rabbit), and hemotrichorial (rat, mouse) organizations. The hemochorial condition is subdivided into labyrinthine pattern in rat, guinea pig, rabbit, and mouse, and a villous arrangement in man.
