    "definition": "The development of an embryo and fetus from fertilisation to birth, conventionally divided in humans into the germinal stage of about the first two weeks, the embryonic stage to about eight weeks after fertilisation, when major organs form, and the fetal stage of growth and maturation, with processes the registry aliases name such as development of the respiratory system, where the lungs mature late and surfactant production matters for preterm babies, fetal development and antenatal development, and prenatal perception, the development of fetal senses, where questions such as when a fetus can feel pain are debated by scientists and bodies, with positions attributed. Development is affected by genetics, maternal health, nutrition and exposures such as alcohol, smoking and some medicines. The registry parent points to prenatal development itself.",
