Placenta (Task 3) Flashcards
Forms the outer layer of the chorion
Trophoblast
Forms inner layer of chorion
Mesoderm
Where nutrient exchange between mother and fetus occurs
Intervillous Spaces
Produce hCG
Trophoblast Cells
Role of hCG
Maintains Corpus Luteum so Progesterone can still be produced
Role of Human Placental Lactogen (HPL)
Adjusts maternal metabolism to ensure fetus receives sufficient nutrition e.g., reduced insulin sensitivity, increases lipolysis
Immunoglobulin which can traverse the placenta
IgG
Placenta Praevia
Placenta overlying cervical os
Cause of pre-eclampsia
Insufficient invasion of trophoblast cells leading to maladaptive spiral arteries
Vasa Praevia
Umbilical cord laying over cervical os
