The correct Answer is:
**Step-by-Step Solution:** 1. **Identify the Buffers in Blood:** The primary buffers in blood are carbonic acid (H2CO3) and bicarbonate (HCO3^-). 2. **Understanding Carbonic Acid Formation:** Carbonic acid is formed when carbon dioxide (CO2) dissolves in water (H2O) in the blood. This reaction is crucial for maintaining pH balance. 3. **Normal pH Range of Blood:** The normal pH range of blood is between 7.30 and 7.40. This range is essential for proper physiological functions. 4. **Effects of pH Disturbance:** - If the pH of blood decreases below 7.30, it leads to a condition known as acidosis. - If the pH rises above 7.40, it results in alkalosis. 5. **Consequences of Acidosis and Alkalosis:** Both acidosis and alkalosis can have severe health implications and may even lead to death if not corrected. 6. **Conclusion:** Therefore, the main buffers in blood are carbonic acid (H2CO3) and bicarbonate (HCO3^-). **Final Answer:** The main buffers in blood are carbonic acid (H2CO3) and bicarbonate (HCO3^-). ---
