Other questions in this quiz
2. why does fetal haemoglobin need a higher affinity for oxygen
- it needs to associate with oxygen in areas where oxygen tension is low enough for mother's haemoglobin to dissociate
- it needs more oxygen
3. how are H+ ions removed from the RBC?
- they associate with haemoglobin to form haemoglobinic acid
- they react with the chloride ions
4. chloride shift
- the movement of chloride ions into the RBCs to balance the charge as hydrogencarbonate ions leave the cell
- the influx of chloride ions into a cell
5. countercurrent flow maintains a steep concentration gradient across the whole lamellae
- true
- false - it ensures equilibrium
