Pregnancy Terms & Definitions
This is the tissue that is created to connect the mother and fetus. About a week after conception, the placenta begins to secrete the hormone
human chorionic gonadotrophin (hCG). This hormone prolongs the lifespan of the corpus luteum as well as stimulates production of progesterone. During
pregnancy, the placenta transports nourishment and takes away waste. Under normal circumstances, your blood does not flow directly into the baby, nor does your baby's blood
enter your bloodstream. Among many other tasks, the placenta serves as a blood filter, keeping your blood on one side and that of your baby on the other. Toxins and other
substances, however, can pass through the membrane - so be careful what you ingest and breathe!
