Oxygenation occurs in the placenta. After this blood then returns to the fetus via the umbilical vein.
Fetal Lung
in my nob
to the lungs for oxygenation then to blood stream
Blood is oxygenated in the lungs!
The blood pressure would be unsustainable and arteriosclerosis would occur
Oxygenation of blood
A vessel called the ductus arteriosus (aka ductus Botalli) connects the pulmonary artery to the aorta in a developing fetus. Along with the foramen ovale, the hole connecting the fetal atria, this opening allows venous blood to bypass the non-functional lungs of the fetus and be pumped back into the arteries. Until birth, the oxygenation of fetal blood is through the umbilical cord.
pump blood for oxygenation and circulation
lungs
Precautions for preventing fetal exposure to HIV-infected maternal blood include avoiding: amniocentesis, fetal scalp blood sampling, premature rupturing of the fetal membranes.
in a fetus blood does not reach the lungs for purification. In a baby blood goes to the lungs for oxygenation.
oxygenation is the answer i found somewhere else
