Current Question (ID: 14366)

Question:

Which of the following statements is correct regarding CO₂ and O₂ transport in blood?

Options:

1. 100 ml of oxygenated blood carries 53 ml of O₂
2. 100 ml of blood always transport equal amounts of O₂ and CO₂
3. 100 ml of oxygenated blood delivers more O₂ than CO₂ to the tissues
4. O₂ and CO₂ are both maximally transported through the blood plasma

Solution:

In normal conditions, hemoglobin carries most of the oxygen in the blood (98%) in the form of oxyhemoglobin, while a small amount (2%) is dissolved in the plasma. On the other hand, carbon dioxide is transported in the blood in three forms: dissolved in plasma (10%), as bicarbonate ion (70%), and carbamino compounds (20%). Therefore, 100 ml of oxygenated blood delivers more oxygen (approximately 20 ml) to the tissues than carbon dioxide (approximately 5-6 ml). Additionally, the amount of oxygen and carbon dioxide transported in the blood can vary depending on the activity level of the individual, metabolic demands, and other factors.
