The amniotic sac is filled with clear fluid called amniotic fluid. The function of the amniotic fluid is: serves to cushion the unborn baby from jolts and bumps. allows the baby to move freely and exercise growing muscles. maintains a constant temperature for the baby.

The First Trimester: 0 – 12 weeks Fetus is fully formed – arms, legs, fingers, toes. Organs are fully formed but do not function (except heart) Reproductive organs form but not distinguishable on ultrasound

The Second Trimester: 13 – 26 weeks Organs mature and begin to function Bone replaces cartilage Hair grows on skin Sex becomes evident Fetus increases in length

The Third Trimester: 27 – 40 weeks Organs fully mature Fetus grows in length and mass
