In the Haemo-Endothelial type of placenta, all barriers except endothelium of fetal part get disintegrated. The epithelium of fetus is also broken so endothelium of fetus directly comes in contact with maternal blood. This type of placenta is seen in Rat, Rabbit etc.

So the correct option is 'True'
