The Human Placenta
some cool stuff I learnt from a podcast
Placental protein 13 creates a diversion, it goes to some other part of the uterus that the placenta isn’t trying to invade and attracts the attention of the immune system. Human placental lactogen can cause pre-eclampsia, dangerously high blood pressure leading to organ failure. By the third trimester, 25% of the blood flow is going into the placenta.
