Acid-Base Balance: Understanding the body's pH regulation through chemical reactions and organ function.
Diagram illustrating acid-base balance in the body, showing the chemical reaction CO₂ + H₂O ⇌ H₂CO₃ ⇌ H⁺ + HCO₃⁻, a pH scale from acidic to basic, a seesaw balancing acid and base, and a kidney with ureter.
