What causes levels of amniotic fluid to be elevated? . Congenital defects - The higher the fluid level, the increased chance of a congenital defect. These birth defects hi…nder swallowing, which can prohibit ingestion of the amniotic fluid, resulting in build up of fluid. Other birth defects could also include intestinal tract blockage or neurological abnormalities.. Rh Factor - As screening for the Rh factor has increased, this is no longer a common cause of elevated fluid levels.. Maternal Diabetes - Experts have found some correlation between diabetes and too much amniotic fluid.. Twin-to-twin transfusion syndrome - This is a complication that can affect identical twin pregnancies. This syndrome is when one baby gets too much blood flow and the other too little due to connections between blood vessels in their shared placenta.. Unknown Reasons - According to the Center for Maternal Fetal Medicine, about 65% of cases of polyhydramnios are due to unknown causes.. What are the risks of having too much amniotic fluid? . Most cases of polyhydramnios are mild and result in few, if any, complications. Those with higher levels of fluid could experience one or more of the following risks:. Premature rupture of the membranes (PROM) . Placental abruption . Preterm labor and delivery (approximately 26%) . Growth restriction (IUGR) resulting in skeletal malformations . Stillbirth occurs in about 4 in 1000 pregnancies that suffer from polyhydramnios vs. about 2 in1000 pregnancies with normal fluid levels. . Cesarean delivery . Postpartum hemorrhage . What are the treatments for elevated amniotic fluid levels? . Many cases of polyhydramnios are easily treated and do not result in complications if the pregnancy is monitored closely. Monitoring would include frequent sonograms measuring growth, biophysical profile and fetal assessment. Other treatments could include:. Medication that can reduce fluid production and are as much as 90% effective. This treatment is not used after 32 weeks gestation because of possible complications. . Amnioreduction is a procedure that can be used to drain excess fluids. This is done through amniocentesis, which may carry certain risks. There is, however, the chance that fluid could build back up even after draining. . Delivery of the baby . Last Updated: 01/2007. The amniotic fluid is part of the baby's life support system. It protects your baby and aids in the development of muscles, limbs, lungs and the digestive system. Amniotic fluid is produced soon after the amniotic sac forms, about 12 days after conception. It is first made up of water that is provided by the mother. After about 20 weeks into the pregnancy, it is primarily made up of fetal urine. As the baby grows, he or she will move and tumble in the womb with the help of the amniotic fluid. In the second trimester the baby will begin to breathe and swallow the amniotic fluid. Amniotic fluid levels increase regularly until about 32-33 weeks gestation, and then they level off. In some cases the amniotic fluid may measure too low or too high. Normal fluid levels may vary, but are usually considered an AFI of 5-25 centimeters or a fluid level of about 800-1000 mL. If the measurement of amniotic fluid is too low it is called oligohydramnios. If the measurement of amniotic fluid is too high it is called polyhydramnios. http://www.americanpregnancy.org
I don't know about the amniotic fluid, but after my own birth the midwife told me my placenta was 1.5 lbs, and said that was a good healthy size. So I would speculate that a p…lacenta is usually over one pound and under two pounds. Hope that helps!
Your baby is formed out of fertilized ovum. During development of the embryo, a sac is formed around the fetus from the extra embryonic cells. This sac contains fluid in it. T…ogether with fluid in it, this sac forms the softest cushion for your baby can have.
The Purpose of the amniotic sac is to hold the baby in the uterus(which holds the amniotic sac), until the process of labor. It contains a fluid. The umbiliical cord forms and… conects to the baby's belly button. when people say, "my water broke", it means that the baby is fully grown and the amniotic sac has popped. The baby travels through the birth canal (cervix) and through the passageway of a baby during the birthing process (Vagina). You can find the before birth, during birth, and after birth processes in the Prentice Hall science book AKA Human Biology and Health. The chapter which contains this information is chapter 7, Reproduction and Development. Be sure to test yourself so you no the material well at the section reviews, The study guide (summarizing Key Concepts), Reviewing key terms, and the chapter review. Be sure to check over your work by looking through the chapter to see if your answers are right. Thank You for reading my summary and I hope you learned alot:)...
It is the tissue that envelopes a baby in the womb, and contains the Amniotic fluid. This is what is referred to as "water breaking" when the sac is ruptured prior to birth.

Why does a baby what?
The amniotic sac holds the fetus (undeveloped baby) and it also holds the amniotic fluid (the fluid helps vibrations from outside the womb, such as the mother falling down on …her stomach region and it also provides nutrients for the fetus starting at about the third month). The sac its self contains the fetus, amniotic fluid, the placenta and the umbilical cord.
