Blood from the mother is used by the fetus.
A fetal pig liver has four lobes in their liver. These four lobes are used for blood filtering nutrients and toxins in their bloodstream.
The ductus venosus shunts most of the left umbilical vein blood flow directly to the inferior vena cava. This allows relatively highly oxygenated blood from the placenta to bypass the liver and get to the fetal brain.
FalseAdult hemoglobin has less affinity for oxygen than fetal hemogloblin. That is why, as an adult female's blood passes BY the placenta, the oxygen diffusses into the fetal blood. Likewise, adult blood, having explelled the carbon dioxide during exhalation, has less concentration of carbon-dioxide than the fetal blood, so it diffuses out of fetal blood into the adult blood. That way, the fetus doesn't need respiration as an oxygen source, nor as a way to rid of waste and carbon dioxide.
The mother sow provides all the nutrients needed by the fetus until birth. Directly into the blood stream.
The Chorion is one of the membranes that exists during pregnancy between the developing fetus and it's mother. It allows the transfer of nutrients from the maternal blood to the fetal blood.
Fetal Lung
The maternal and fetal circulatory systems are separated by the placental barrier; some molecules (for example nutrients, oxygen, and certain proteins) are able to pass through, but "blood" doesn't. Injuries could result in the blood mixing, but this is a bad thing and is not supposed to happen to any significant degree.
Due to the placenta and the exchange of nutrients and waste products from the fetal to the maternal circulation the fetal kidneys are not that important to the baby's health.
Precautions for preventing fetal exposure to HIV-infected maternal blood include avoiding: amniocentesis, fetal scalp blood sampling, premature rupturing of the fetal membranes.
to digest the food and absorb the nutrients
blood only carries our nutrients. nutrients are transported by blood.
The fetal circulation is the circulatory system of a human fetus, often encompassing the entire fetoplacental circulation that also includes the umbilical cord and the blood vessels within the placenta that carry fetal blood.The fetal circulation works differently from that of born humans, mainly because the lungs are not in use: the fetus obtains oxygen and nutrients from the mother through the placenta and the umbilical cord.
