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.
