The Haldane Effect refers to the physiological phenomenon where deoxygenated blood can carry more carbon dioxide (CO2) than oxygenated blood. This effect is crucial for efficient gas exchange in the lungs and tissues. When hemoglobin releases oxygen, it changes shape, allowing it to bind more CO2 and hydrogen ions, which helps transport waste products from the body's metabolism. This effect is named after the British scientist J.B.S. Haldane, who studied the relationship between oxygen and carbon dioxide transport in the blood. The Haldane Effect enhances the removal of CO2 from tissues and promotes its release in the lungs, facilitating respiration and maintaining acid-base balance in the body.
