What is amniotic fluid, the water that breaks before childbirth, made of?

gdec1

Amniotic fluid is the watery liquid surrounding and cushioning a growing fetus within the amnion. It allows the fetus to move freely without the walls of the uterus being too tight against its body. Buoyancy is also provided. The amnion grows and begins to fill, mainly with water, around two weeks after fertilisation. After a further 10 weeks the liquid contains proteins, carbohydrates, lipids and phospholipids, urea and electrolytes, all which aid in the growth of the fetus. http://en.wikipedia.org/wiki/Amniotic_fluid Aug 26 06, 12:54 AM

The amniotic sac that contains the embryo forms about 12 days after conception. Amniotic fluid immediately begins to fill the sac. In the early weeks of pregnancy, amniotic fluid consists mainly of water supplied by the mother. After about 12 weeks, fetal urine makes up most of the fluid. http://www.marchofdimes.com/professionals/681_4536.asp Aug 26 06, 7:59 AM
