functi 2. A developing fetus obtains oxygen from its mother's blood. In an organ called the placenta, fetal capillaries run through and exchange substances with maternal blood. The hemoglobin made by a fetus has different properties than that made after birth. At low oxygen levels, fetal hemoglobin binds oxygen more strongly than normal hemoglobin does. How does fetal hemoglobin's somewhat higher affinity for oxygen benefit a fetus? 3. Icefish live in the extremely cold ocean near Antarctica.
