PLACENTAL MEASUREMENT

Patent Granted The placenta is an organ that connects the developing fetus to the uterine wall to allow nutrient uptake, waste elimination, and gas exchange via the mother's blood supply, fights against internal infection and produces hormones to support pregnancy. Placentas are a defining characteristic of placental mammals, but are also found in some non-mammals with varying levels of development.[1] Note, however, that the homology of such structures in various viviparous organisms is debatable and, in invertebrates such as Arthropoda, is analogous at best.
