many per unit volume hence carry more oxygen and carbon IV oxide
biconcave in shape to provide large surface area for absorption of oxygen and carbon IV oxide
absence of nucleolus hence more haemoglobin to carry sufficient oxygen and carbon IV oxide
alter shape to be able to pass through the narrow lumen of capillaries to deliver or supply oxygen and carry away carbon IV oxide
have haemoglobin with high affinity for uptake of oxygen and carbon IV oxide
