"WebThe left-shifted oxygen binding curve of hemoglobin means that the hemoglobin in these animals binds to oxygen more readily at lower partial pressures of oxygen. This adaptation allows them to extract more oxygen from the relatively low levels of oxygen available in their lung and blood during a dive. " - Oxygen binding curve

WebNov 13, 2024 · Overall positioning of the oxyhemoglobin dissociation curve can be determined from the P50, which is the arterial oxygen tension at which hemoglobin is 50% saturated. As hemoglobin’s affinity for oxygen decreases, oxygen is more readily unloaded at the tissue level. This is reflected in a rightward shift of the curve and a higher P50. WebJan 17, 2024 · The oxygen dissociation curve shows the amount of oxygen saturated in hemoglobin for a given partial pressure of oxygen. The curve shifts right when oxygen’s …
