Mysterious and mighty, the placenta belongs to both the mother and the fetus. It grows in the uterus and hooks onto the mother's body to provide her fetus with oxygen, nutrients and blood. Find 15 more amazing facts about the placenta that you might not have known below!

  4. About 20 percent of your blood supply passes through the placenta every minute (wow)!

  5. The placenta is a multifunctional organ. It acts as baby's lungs (to supply oxygen and remove carbon dioxide), babies kidneys (to filter out waste), and used to secrete essential hormones to support the pregnancy.

  6. The placenta is developed from a fertilized egg, which means it is made from both mom and dad's genes.

  7. The placenta begins to form just 6-7 days after conception and grows as your baby grows!
