The placenta is an organ attached to the lining of your uterus during pregnancy.
It keeps your unborn baby’s blood supply separate from your own blood supply, as well as providing a link between the two. This link allows the placenta to carry out functions that your unborn baby can’t perform for itself.
Oxygen and nutrients pass from your blood supply into the placenta. From there, the umbilical cord carries the oxygen and nutrients to your unborn baby. The placenta produces hormones that help your baby grow & develop and towards the end of your pregnancy the placenta passes antibodies from you to your baby, giving them immunity for about 3 months after birth.
