The 36 pages that link to Placenta, each with the reason it gives.

• MammalRelated: In placental mammals, it sustains development inside the uterus.

• PregnancyBroader topic: It becomes the central interface sustaining fetal growth in the uterus.

• MarsupialCompared with: Marsupials generally rely less on prolonged placental support than placental mammals.

• MammaliaRelated: Placental development supports pregnancy in most living mammal lineages.

• ViviparityRelated: In placental viviparity, it supplies embryos with nutrients and oxygen while removing waste.

• AmnioteRelated: In placental mammals, it adapts amniote membranes to development inside the mother.

• Ectopic pregnancyRelated: Placental tissue develops at the implantation site and produces pregnancy hormones.

• UterusRelated: It develops at the uterine interface to sustain pregnancy.

• OvoviviparityCompared with: Most ovoviviparous embryos lack the placental nutrient exchange characteristic of many live-bearing species.

• GonadCompared with: The placenta produces hormones during pregnancy but is not a gamete-producing organ.

• Marsupial pouchCompared with: Placental mammals support more development before birth, unlike the usual pouch-centered marsupial pattern.

• Fetal circulationNarrower topic: It performs the gas exchange that fetal lungs do not yet provide.

• Alkaline phosphataseRelated: Placental tissue produces another alkaline phosphatase form, especially during pregnancy.

• Marsupial reproductionRelated: Marsupials form placental connections, but fetal development before birth is usually limited.

• AromataseRelated: Placental aromatase produces estrogens during pregnancy and limits fetal androgen exposure.

• EutheriaRelated: Placental development is associated with living eutherians but does not alone define the entire clade.

• Gestational diabetesRelated: Placental hormones contribute to the insulin resistance underlying gestational diabetes.

• Fetal alcohol spectrum disorderRelated: Alcohol crosses the placenta, exposing the developing fetus to the substance consumed during pregnancy.

• GestationRelated: It supplies oxygen and nutrients and removes waste during gestation.

• ObstetricsRelated: Its function supports fetal growth, and its disorders can endanger pregnancy.

• YolkCompared with: In many mammals, placental transfer reduces dependence on a large yolk reserve.

• Developmental toxicityRelated: Its structure and function influence fetal exposure, though it does not block every toxicant.

• PlacentaliaRelated: Placental mammals sustain fetal development through this maternal-fetal interface.

• TrophoblastRelated: Trophoblast forms the fetal component of this exchange organ.

• Prenatal ultrasonographyRelated: Its position and appearance are assessed alongside fetal anatomy.

• RubellaRelated: Rubella virus can cross this organ and infect the developing fetus.

• FetusRelated: It supplies the fetus and removes waste while keeping maternal and fetal blood largely separate.

• Umbilical cordRelated: The cord connects the fetus to this exchange organ.

• Amniotic fluidRelated: Placental function affects fetal circulation and can influence amniotic-fluid balance.

• Animal embryonic developmentRelated: Placental development supports embryos that remain inside the maternal body.

• Viviparous lizardRelated: In this lizard, maternal tissues support embryos, though nourishment remains largely yolk-based.

• Embryonic structuresRelated: It is a major extraembryonic structure that supports development without becoming part of the embryo.

• Fish pregnancyBroader topic: In a few live-bearing fish, specialized maternal and embryonic tissues form placenta-like nutrient-exchange structures.

• Molar pregnancyCompared with: Normal placental development provides the baseline against which molar tissue is abnormal.

• NavelRelated: It connects to the fetus through the cord that leaves the navel after birth.

• Obstetrics and gynaecologyRelated: Placental function is central to fetal growth and many pregnancy complications.
