Pulmonary vein
The highest oxygen affinity is demonstrated by fetal hemoglobin (HbF), due to its higher affinity for oxygen compared to adult hemoglobin (HbA). This allows for efficient oxygen transfer from the mother to the fetus in the placenta.
I think the answer shall be divided in to 2 parts , physical and mental . Physical of the adolescent is growing at the highest speed while adult is matured . Mentally , adolescent is having no direction while adult is more concentration .
FalseAdult hemoglobin has less affinity for oxygen than fetal hemogloblin. That is why, as an adult female's blood passes BY the placenta, the oxygen diffusses into the fetal blood. Likewise, adult blood, having explelled the carbon dioxide during exhalation, has less concentration of carbon-dioxide than the fetal blood, so it diffuses out of fetal blood into the adult blood. That way, the fetus doesn't need respiration as an oxygen source, nor as a way to rid of waste and carbon dioxide.
