Answer:
E.
Explanation:
A fetus is able to extract O2 from its mother's blood because fetal hemoglobin has a higher affinity for O2 than maternal hemoglobin. Thus making it alot easier for the hemoglobin to bind to oxygen. This causes the oxygen-dissociation curve to move towards the left of the maternal oxygen-dissociation curve.
Answer:
E. Fetal hemoglobin has a higher affinity for O2 than maternal hemoglobin.
Explanation:
Hemoglobin is a protein found in the blood which is responsible for binding to oxygen for efficient circulation to other parts of the body.
Fetal hemoglobin is usually at a high level and it’s produced around 6 weeks of conception. The fetal hemoglobin has a higher affinity for Oxygen than that of the maternal hemoglobin and it helps in carrying oxygen from the bloodstream of the mother to cells and tissues of the fetus.
