  2. Amniotic sac - Wikipedia

    en.wikipedia.org/wiki/Amniotic_sac

    Amniotic cavity in human embryo 1.3 mm. long. The amniotic cavity is the closed sac between the embryo and the amnion, containing the amniotic fluid. The amniotic cavity is formed by the fusion of the parts of the amniotic fold, which first makes its appearance at the cephalic extremity and subsequently at the caudal end and sides of the embryo ...

  3. Amniotic fluid - Wikipedia

    en.wikipedia.org/wiki/Amniotic_fluid

    The amniotic fluid is the protective liquid contained by the amniotic sac of a gravid amniote. This fluid serves as a cushion for the growing fetus, but also serves to facilitate the exchange of nutrients, water, and biochemical products between mother and fetus. For humans, the amniotic fluid is commonly called water or waters (Latin liquor ...

  4. Amnion - Wikipedia

    en.wikipedia.org/wiki/Amnion

    This, the amniotic fold, first makes its appearance at the cephalic extremity, and subsequently at the caudal end and sides of the embryo, and gradually rising, its different parts meet and fuse over the dorsal aspect of the embryo, and enclose a cavity, the amniotic cavity. This kind of amnion is known as pleuroamnion (formed by folding), as ...

  5. Fetal membranes - Wikipedia

    en.wikipedia.org/wiki/Fetal_membranes

    The amnion is the innermost layer and, therefore, contacts the amniotic fluid, the fetus and the umbilical cord. [5] The internal pressure of the amniotic fluid causes the amnion to be passively attached to the chorion. [4] The chorion functions to separate the amnion from the maternal decidua and uterus. [4]

  6. Gestational sac - Wikipedia

    en.wikipedia.org/wiki/Gestational_sac

    The gestational sac is spherical in shape, and is usually located in the upper part (fundus) of the uterus.By approximately nine weeks of gestational age, due to folding of the trilaminar germ disc, the amniotic sac expands and occupy the majority of the volume of the gestational sac, eventually reducing the extraembryonic coelom (the gestational sac or the chorionic cavity) to a thin layer ...

  7. Artificial womb - Wikipedia

    en.wikipedia.org/wiki/Artificial_womb

    An artificial uterus, sometimes referred to as an "exowomb", [13] would have to provide nutrients and oxygen to nurture a fetus, as well as dispose of waste material. The scope of an artificial uterus, or "artificial uterus system" to emphasize a broader scope, may also include the interface serving the function otherwise provided by the placenta, an amniotic tank functioning as the amniotic ...

  8. Amniocentesis - Wikipedia

    en.wikipedia.org/wiki/Amniocentesis

    Amniotic fluid embolism, a condition in which amniotic fluid or other fetal debris enters the maternal circulation, is an extremely rare and catastrophic complication of amniocentesis. [1] Amniotic fluid embolism can result in cardiovascular collapse and has a poor maternal prognosis. [ 43 ]

  9. Oligohydramnios - Wikipedia

    en.wikipedia.org/wiki/Oligohydramnios

    Low amniotic fluid can be attributed to a maternal, fetal, placental or idiopathic cause and can result in poor fetal outcomes including death. The prognosis of the fetus is dependent on the etiology, gestational age at diagnosis, and the severity of the oligohydramnios.
