Haldane Effect

The Haldane Effect describes how the blood's ability to carry carbon dioxide (CO₂) changes depending on oxygen levels. When oxygen binds to hemoglobin in the lungs, hemoglobin's capacity to pick up CO₂ from the body increases. Conversely, in tissues where oxygen is released, hemoglobin releases CO₂ more readily for removal. This process helps the body efficiently exchange gases: oxygen is absorbed in the lungs, and CO₂ is expelled, with hemoglobin adjusting its CO₂-carrying capacity based on oxygen binding, optimizing gas transport during respiration.
