Fetal hemoglobin (HbF) is a special type of hemoglobin found in fetuses, characterized by its higher affinity for oxygen compared to adult hemoglobin (HbA). This adaptation is crucial during prenatal development, as it allows the fetus to effectively extract oxygen from maternal blood while in the low-oxygen environment of the uterus. The unique structure of HbF facilitates gas transport and supports the developing tissues and organs of the fetus.
