What makes a placenta unhealthy?
Causes of insufficiency Placental insufficiency is linked to blood flow problems. While maternal blood and vascular disorders can trigger it, medications and lifestyle habits are also possible triggers. The most common conditions linked to placental insufficiency are: diabetes.
Why is the placenta called Metadiscoidal?
Initially the chorionic villi are distributed on the whole surface of blastocyst but later the major part of blastocyst is exposed and choroinic villi disappear from the expose part and remain only on a disc like area to form metadiscoidal placenta. So the human Placenta is chorionic and metadiscoidal.
