if someone can tell me wats on this page i will be so grateful its 2008-2009 kaplan edition
Oxygen-haemoglobin dissociation curve
in addition to factors shifting the curve :
Left shift of the curve is a sign of haemoglobin's increased affinity for oxygen (eg. at the lungs). Similarly, right shift shows decreased affinity, as would appear with an increase in body temperature, hydrogen ion, 2,3-diphosphoglycerate (also known as bisphosphoglycerate) or carbon dioxide concentration (the Bohr effect)
Carbon monoxide has a much higher affinity for haemoglobin than oxygen does. In carbon monoxide poisoning, oxygen cannot be transported and released to body tissues thus resulting in hypoxia.
With foetal haemoglobin, the shift facilitates diffusion of oxygen across the placenta. The oxygen dissociation curve for myoglobin exists even further to the left.
hope that help you , GL
thank u so much u really helped me a lot
i'm so grateful
