Topic 7: Gaseous Exchange and Its Control
• Describe three ways of carbon dioxide transport from respiring

Significance
Adaptation
Has biconcave shape to increase the surface area for effective gaseous exchange
No nucleus to provide more space for haemoglobin storage
Has elastic membrane to change the shape easily / ease the movement in blood
capillary
No mitochondria to prevent the transported O2 be consumed
