A baby’s first organ is the least explored
At the same time as an embryo’s own organs are developing, the placenta removes waste products and supplies the baby with oxygen and nourishment. But a child’s first organ is one of those about which we know the least. The placenta is closely linked with blood vessels in the womb wall, but we do not know how it is dislodged immediately after birth. The cause of many common pregnancy complications such as very premature delivery, is probably to be found in the close interaction between placenta and womb.
