What is placenta and how is it formed?
The placenta is an organ that develops in the uterus during pregnancy. This structure provides oxygen and nutrients to a growing baby. It also removes waste products from the baby’s blood. The placenta attaches to the wall of the uterus, and the baby’s umbilical cord arises from it.
When is the placenta fully formed?
18 to 20 weeks
This arrangement greatly increases the area of contact between the wall of the uterus and the placenta, so that more nutrients and waste materials can be exchanged. The placenta is fully formed by 18 to 20 weeks but continues to grow throughout pregnancy. At delivery, it weighs about 1 pound.
