Asked by Akanksha Mishra | 19 Oct, 2013, 12:22: AM
Expert Answer
The placenta is formed of two sets of villi. One set is arises from the uterus of mother and the other set is from the allantois (protective membrane around the embryo). These villi get interlocked with each other. Here, blood of the embryo and the blood of the mother come in close contact with each other in these villi.
