What is the function of the amniotic sac?
The amniotic sac contains amniotic fluid, which has a number of roles which are important in the development of the fetus. # It acts as a thermal buffer and a shock absorber, and therefore protects the developing fetus. # The fetus drinks the amniotic fluid (this is called fetal respiration) and urinates into it. # It lubricates delivery of the fetus at term. # It is isotonic, so has the same water potential as the blood. # It is exchanged by the fetal skin up to 20 weeks of pregnancy. # It maintains a sterile environment for the fetus. # It aids development of the muscles and bones of the fetus. # Allows free movement of the fetus. # The amniotic sac acts as a hydrostatic wedge during the first stages of labour. Also, cells that are sloughed off from the fetus into the amniotic fluid can be cultured after an amniocentesis to look for genetic conditions such as Down's syndrome, however, this is not really a purpose of amniotic fluid.
