D
bicarbonate
Verified step by step guidance1
Understand the concept of a buffer system: A buffer system helps maintain pH balance in the body by neutralizing excess acids or bases.
Identify the types of buffer systems: Common buffer systems in the body include bicarbonate, phosphate, protein, and hemoglobin.
Focus on extracellular fluid: Extracellular fluid, such as plasma, requires a buffer system that can effectively manage pH changes due to metabolic activities.
Recognize the role of the bicarbonate buffer system: The bicarbonate buffer system is the primary buffer system in extracellular fluid, as it efficiently regulates pH by converting strong acids and bases into weaker ones.
Conclude that the bicarbonate buffer system is the most important for maintaining pH balance in extracellular fluid, such as plasma.
