What is the function of fetal circulation? 

Q image thumb

The fetal circulation is the circulatory system of a human fetus, often encompassing the entire fetoplacental circulation which includes the umbilical cord and the blood vessels within the placenta that carry fetal blood.

35

How does fetal circulation work differently from that of born humans?

Q image thumb

  • The lungs are not in use
  • The fetus obtains oxygen and nutrients from the mother through the placenta and the umbilical cord
