Preferred Label : placental cotyledon;
Uberon definition : Round structure consisting of chorionic villi[PMID]. A separation of the decidua basalis
of the placenta, separated by placental septa. Each cotyledon consists of a main stem
of a chorionic villus as well as its branches and subbranches. The cotyledons receive
fetal blood from chorionic vessels, which branch off cotyledon vessels into the cotyledons,
which, in turn, branch into capillaries. The cotyledons are surrounded by maternal
blood, which can exchange oxygen and nutrients with the fetal blood in the capillaries[WP].;
Uberon synonym : placenta cotyledon;
Uberon related term : discoid placenta;
Uberon broad term : cotyledon;
Uberon Taxon note : Rodents have a single cotyledon (called a discoid placenta), whereas humans have multiple
cotyledons, although they are consolidated into a cluster that resembles a single
disc[PMID:19829370];
