<h3>What is placenta?</h3>
Shortly after implantation, the blastocyst starts to develop into the placenta, a transient organ of the fetus. It is a key endocrine organ that produces hormones that control both maternal and fetal physiology during pregnancy. It also performs crucial roles in regulating nutrition, gas, and waste exchange between the physically separate maternal and fetal circulations.
The placenta forms a species-dependent connection with the mother's uterus on one side and the fetus via the umbilical cord on the other. In humans, the placenta is ejected from the uterus along with a thin layer of maternal decidual (endometrial) tissue, which is frequently mistakenly referred to as the "maternal component" of the placenta.
