Q&A: What does the placenta do?

Where does the placenta come from? What exactly does it do?

Re: Where does the placenta come from? What exactly does it do?

The Bump Expert

Once you're officially pregnant, your future baby consists of a little ball of swiftly multiplying cells in your uterus. Some of the cells in this bundle will grow into the embryo (which will soon start forming baby-parts), and others will grow into the placenta. So essentially, the placenta comes from the same roots as your child (perhaps explaining why some cultures refer to it as baby's "twin").

And what of this placenta? Well, it's got a pretty big role -- it is the vital connection between your body and baby's. Its full functions are complex, but basically, it takes goodies like oxygen and nutrients from your blood and moves them into baby's blood to help him stay alive and grow. It also filters waste from baby's blood and dumps it into yours (to be disposed of by your blood). The placenta is also the route by which damaging substances like drugs, alcohol or nicotine could reach baby, so remember to stay away from things that could cause harm! Finger-like growths tuck into the uterine walls to connect the placenta to you, while the umbilical cord connects the placenta to baby.

When you delivery, the squishy placenta (also known as the afterbirth) will follow baby out of your belly. If you give birth in a hospital, they will generally dispose of the organ as medical waste, but if you'd like to have a look before it's trashed, just ask -- most docs will oblige. Some women choose to keep the placenta and bury it, burn it our even dry it out and take it as a supplement (it's rumored to increase youthfulness and combat postpartum depression).

Q&A: What does the placenta do?

Twin girls. Faternal with fused placenta. Babys are 8 lbs. and 71/2 lbs. at 36 weeks. I'm 1 cm. dilated and having preassure and pain down very low. Saw Dr. yesterday and was told go home and rest. Can,t get a for sure answer from Dr. about fused plcenta and if I will need C-section. Won,t placenta be delivered with baby A? Baby B,s plcenta is fused with Baby A. Dr. says this happens all the time with twins. Heads are down and everything looks great. What about the fused placents ?
