Question

What's the hemoglobin of a healthy person ​

Answer 1

• The oxygen is needed for aerobic respiration and diffuses from a region of high to low concentration from the mother's blood to the blood of the foetus.
• The haemoglobin of the foetus has a higher affinity for oxygen than that of adult haemoglobin and so the efficiency of exchange is increased

So, the correct answer is 'Has a higher affinity for oxygen than that of an adult'
