Question

what is the difference between non deciduate and contra deciduate placenta ?!​

Answer 1

Answer:

This type of placenta is called non-deciduate or non- deciduous placenta and is found in pigs, cattle and some other mammals. Further, the chorionic villi of a non-deciduate placenta, because lie in apposition with the endometrium, but, do not fuse with it, so such a placenta is also called semiplacenta.
