Oxygen Saturation Curve

The oxygen saturation curve shows how easily hemoglobin in your blood picks up and releases oxygen. When oxygen levels are high, hemoglobin binds oxygen efficiently, like at the lungs. As oxygen levels drop, hemoglobin releases oxygen more readily to tissues needing it. The curve has an S-shape, meaning hemoglobin's oxygen affinity increases as it binds oxygen, making loading in the lungs efficient, and decreases when oxygen levels are low, facilitating delivery to tissues. This balance ensures your body gets enough oxygen where needed, adjusting to varying conditions effectively.
