Asked by vinny | 26 Feb, 2013, 12:13: PM
answered-by-expert Expert Answer

The placenta is an organ that links the budding fetus to the uterine wall to facilitate the uptake of nutrients, gas exchange and waste elimination, with the help of the mother’s blood supply. The umbilical cord connects the fetus to the placenta.

The placenta is a spongy mass of flesh that absorbs oxygen and nutrients from the blood stream of the mother, which are then transferred to the baby via the umbilical cord. The umbilical cord is responsible for carrying the oxygen and nutrients to the fetus.

The placenta is discarded after the baby’s delivery, while a portion of the umbilical stump still remains on the baby, but soon withers away as well.
