The fetus obtains oxygen and nutrients from the mother through the placenta and the umbilical cord. [25] Blood from the placenta is carried to the fetus by the umbilical vein. About half of this enters the fetal ductus venosus and is carried to the inferior vena cava, while the other half enters the liver proper from the inferior border of the ...
Fetus in fetu (or foetus in foetu) is a rare developmental abnormality in which a mass of tissue resembling a fetus forms inside the body of its twin. An early example of the phenomenon was described in 1808 by George William Young. [1] There are two hypotheses for the origin of a fetus in fetu.
Fetus or Foetus may also refer to: Foetus (band) Foetus, a 1994 Hungarian film; Fetus in fetu, a developmental abnormality; Campylobacter fetus, a species of bacteria
The fetal membranes separate maternal tissue from fetal tissue at a basic mechanical level. The fetal membrane is composed of a thick cellular chorion covering a thin amnion composed of dense collagen fibrils. The amnion is in contact with the amniotic fluid and ensures structural integrity of the sac due to its mechanical strength.
The placenta (pl.: placentas or placentae) is a temporary embryonic and later fetal organ that begins developing from the blastocyst shortly after implantation.It plays critical roles in facilitating nutrient, gas and waste exchange between the physically separate maternal and fetal circulations, and is an important endocrine organ, producing hormones that regulate both maternal and fetal ...
Abortion is the termination of a pregnancy by removal or expulsion of an embryo or fetus. [nb 1] [2] An abortion that occurs without intervention is known as a miscarriage or "spontaneous abortion"; these occur in approximately 30% to 40% of all pregnancies.

[ 59 ] [ page needed ] In many countries, parents are expected by friends and family members to recover from the loss of an unborn baby very soon after it happens ...
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 ...
