Q
  • Role of Placenta
  • Poor implementation can lead to?
  • What does Placenta produces?
A
  • site of fetal nutritive, respiratory, and excretory function
  • discoid mass composed of fetal (chorion frondosum) and maternal (decidua basalis) tissues
    divided by ssures into cotyledons (lobules) on the uterine side
  • produces hormones such as progesterone, placental lactogen, estrogen, relaxin, β-hCG, and
    IGFs
  • poor implantation can lead to spontaneous abortion
  • abnormal location, implantation, or detachment can lead to antepartum hemorrhage
    (see Obstetrical Hemorrhage, OB14)
