The placenta (pl.: placentas or placentae) is a temporary embryonic and later fetal organ that begins developing from the blastocyst shortly after implantation. It plays critical roles in facilitating nutrient, gas and waste exchange between the physically separate maternal and fetal circulations, and is an important endocrine organ , producing ...

The journal Placenta publishes high-quality original articles and invited topical reviews on all aspects of human and animal placentation, and the interactions between the mother, the placenta and fetal development, genetics and epigenetics, stem cells, transport, immunology, pathology, pharmacology, cell and molecular biology, and ...

2023年10月26日 · The placenta is a temporary organ of pregnancy situated in the uterus. It is formed from fetal and maternal components. The fetal portion is formed by the chorion frondosum, while the maternal portion is formed by the decidua basalis. Moreover, the placenta is the meeting point of two circulatory systems: fetal circulation and maternal circulation.

The placenta is arguably the most important organ of the body, but paradoxically the most poorly understood. During its transient existence, it performs actions that are later taken on by diverse separate organs, including the lungs, liver, gut, ...

2015年7月31日 · Discarded at birth, the placenta is a highly complex and fascinating organ. During the course of a pregnancy, it acts as the lungs, gut, kidneys, and liver of the fetus. The placenta also has major endocrine actions that modulate maternal physiology and metabolism and provides a safe and protective milieu in which the fetus can develop.

2020年11月19日 · Placentas are a defining characteristic of placental mammals but they are found in marsupials and some non-mammals with varying levels of development. At first, the chorionic villi cover the entire surface of the chorion. Later on, the villi opposite the decidua basalis continue to grow and expand to form chorion frondosum.
