to increase libido/prevent post-menstrual bleeding and it is stopped if there is post-menstrual bleeding
46
define pre-eclampsia
refers to increased BP >140/90mmHg after 20 weeks of gestation characterised by proteinuria or end-organ damage due to abnormal formation of spiral vessels of the placenta resulting in increased vascular resistance and reduced fetal-placental flow

gestational - after 20 weeks, no proteinuria
pre-eclampsia
48

73
functions of the placenta
immunisation - allows maternal antibodies to cross
production of hormones - beta HCG (similar to TSH - in hydratiform mole high BHCG leads to hyperthyroidism), HPL, progesterone and oestrogen

gaseous exchange
metabolism
74
