placentae
Womb's nutrient conduits
Placentae is the Latin plural of placenta, the organ that develops in the uterus during pregnancy to nourish the fetus through the umbilical cord.
While placentas is more common in everyday usage, placentae appears in medical and scientific writing.
In botany, placentae refers to the parts of the ovary wall where ovules attach.
The placentae of twin pregnancies were examined separately.
