amniotic fluid in Science
amniotic fluid
  (ām'nē-ŏt'ĭk)   
The watery fluid within the amnion that surrounds the fetus. Amniotic fluid cushions the fetus from injury, allows movement, and helps to stabilize temperature. The composition of the fluid changes over the course of gestation. Initially, amniotic fluid is similar to maternal plasma. As the fetus develops, phospholipids originating from the lungs, fetal cells, lanugo, and urine are deposited in the fluid.
