Amino acids: Substances that act as building blocks in the developing embryo and fetus.

Amniocentesis: Removal of amniotic fluid from the amniotic sac. Fluid is tested for some genetic defects.

Amnion: Membrane around the fetus. It surrounds the amniotic cavity.

Amniotic fluid: Liquid surrounding the baby inside the amniotic sac.

Amniotic sac: Sac that surrounds baby inside the uterus. It contains the baby, the placenta and the amniotic fluid.

Anemia: Any condition in which the number of red blood cells is less than normal. Term usually applies to the concentration of the oxygen-transporting material in the blood, which is the red blood cell.

Congenital problem: Problem present at birth.
