Question

Compare and contrast the relative speed of buffers, the respiratory system, and the kidneys in maintaining the acid-base balance of the blood.

Answer 1

Explanation:

• Chemical buffers : fraction of a second , ties up excess of H+ or bases temporarily.
• Respiratory buffers: within a minute , maintaining or reducing the level of CO2.
• Renal buffers: hours or takes even days, moves away metabolic acid and excess of base.
