  2. 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 ...

  3. Amniocentesis - Wikipedia

    en.wikipedia.org/wiki/Amniocentesis

    Amniotic fluid is composed of fetal cells, urine, and lung secretions. [46] 18-20 mL of amniotic fluid is slowly aspirated, with the first 1-2 mL typically discarded due to higher risk of maternal cell contamination. [2] The remaining sample is submitted for laboratory testing. [1]

  4. Amniotic fluid embolism - Wikipedia

    en.wikipedia.org/wiki/Amniotic_fluid_embolism

    An amniotic fluid embolism (AFE) is a life-threatening childbirth emergency in which amniotic fluid enters the blood stream of the mother, triggering a serious reaction which results in cardiorespiratory (heart and lung) collapse and massive bleeding (coagulopathy).

  5. Oligohydramnios - Wikipedia

    en.wikipedia.org/wiki/Oligohydramnios

    The volume of amniotic fluid typically increases until 36 weeks and starts decreasing after 40 weeks in post-term gestations. [4] For this reason, discrepancies between fundal height measurements and gestational age can be a clinical indication of amniotic fluid abnormality and should be evaluated by ultrasound.

  6. Amnion - Wikipedia

    en.wikipedia.org/wiki/Amnion

    The amniotic fluid allows the free movements of the fetus during the later stages of pregnancy, and also protects it by diminishing the risk of injury from without. It contains less than two percent solids, consisting of urea and other extractives, inorganic salts, a small amount of protein, and frequently a trace of sugar. That some of the ...

  7. Amniotic sac - Wikipedia

    en.wikipedia.org/wiki/Amniotic_sac

    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. As the amniotic fold rises and fuses over ...

  8. Amniocyte - Wikipedia

    en.wikipedia.org/wiki/Amniocyte

    An amniocyte (literally "lamb cell") is a cell of a fetus which is suspended in the amniotic fluid. [1] To study a person's chromosomes, it can be used in DNA-based analysis, via microscopic analysis of the cells in amniotic fluid. After circa 16 weeks of pregnancy the fluid can be collected.

  9. Chorioamnionitis - Wikipedia

    en.wikipedia.org/wiki/Chorioamnionitis

    The amniotic sac consists of two parts: The outer membrane is the chorion. It is closest to the mother and physically supports the much thinner amnion. The chorion is the last and outermost of the membranes that make up the amniotic sac. [13] The inner membrane is the amnion. It is in direct contact with the amniotic fluid, which surrounds the ...
