how blood loads and unloads O₂

Presets
Hemoglobin's S-shaped curve lets blood grab oxygen in the lungs and release it in tissues. The cooperative binding (Hill coefficient > 1) makes the curve steep, so a small pressure drop unloads a lot of O₂. A right shift (higher P50) releases even more where it's needed. Educational tool, not medical advice.
Data Inspector
Saturation here75.1%
At lungs (100 mmHg)97%
At tissue (40 mmHg)75%
Governing equation
Reading this result: Cooperative binding (Hill 2.7) gives the S-shape: the swing from 40 to 100 mmHg moves saturation from 75% to 97%, which is how tissues get their O₂.
