The placenta is an organ that connects the growing fetus to the uterine wall of the Maternal. Together with the umbilical cord, they work as a bridge between the two as the placenta is responsible for the nutrient uptake, thermo-regulation, waste elimination, as well as gas exchange via the mother’s blood supply. During a pregnancy stage, the placenta produces hormones for the development of the fetus, and towards the end of a pregnancy, the placenta passes antibodies from the mother to the baby. This organ keeps a defining characteristic in placental mammals while it presents only varying degrees of development in some non-mammals. Some external factors like harmful substance or the internal factors like growing old have the opportunity to cause the pathological change of placenta which may lead to the failure of pregnancy. Many target proteins of placenta have been used for the special purpose of basic research.
