Vedclass · Answer

(B) : Oxygen is required for aerobic respiration and diffuses from a region of high concentration to a region of low concentration from the mother's blood to the blood of the foetus.The haemoglobin of the foetus $(HbF)$ has a higher affinity for oxygen than that of adult haemoglobin $(HbA)$,which facilitates the efficient transfer of oxygen across the placenta.Carbon dioxide,a waste product of aerobic respiration,diffuses in the opposite direction from the foetus to the mother.
