Fetal hemoglobin's higher affinity for oxygen enables O2 transfer from maternal to fetal blood at the placenta. It's important to lose fetal hemoglobin after birth because its high affinity would hinder O2 release to adult tissues, which aren't adapted to requiring such low O2 concentrations for release.
La mayor afinidad de la hemoglobina fetal por el oxígeno permite la transferencia de O2 desde la sangre materna a la fetal en la placenta. Es importante perder la hemoglobina fetal después del nacimiento porque su alta afinidad dificultaría la liberación de O2 a los tejidos adultos, que no están adaptados a requerir concentraciones de O2 tan bajas para la liberación.
