Amnion - Fluid ▪ Functions ➢ Mechanically cushion ➢ Protect from fetus adhesion ➢ Movement ➢ Maintain Temp ▪ Abnormalities 1) too much (polyhydramnios) >2000 ml Abnormal digestive system or CNS - esophageal atresia - anencephaly 2) too little (oligohydramnios) <500 ml Abnormal urinary system - poor development of kidney - urethra atresia
