Oxygen, mostly, is carried by a pigment in our blood whereas carbon dioxide is transported in dissolved form in our blood.
Give TWO reasons that make the above statement correct.
Answer:
- Oxygen in our blood is carried by Haemoglobin , the red pigment present in RBCs.
- This is because Haemoglobin has a very high affinity for Oxygen as compared to water.
- Similarly, carbon dioxide , due to its high affinity for water , can readily dissolve in the water present in blood to be easily transported.
