Hi everyone!
What is oxygen - haemoglobin dissociation curve or oxygen binding curve?
The oxygen - haemoglobin dissociation curve plots the proportion of haemoglobin in its saturated form on the vertical axis (fractional saturation of hemoglobin) against the prevailing oxygen tension on the horizontal axis.
What does it tell?
It tells you the affinity of hemoglobin for oxygen.
How does it do that?
It's simple!
If the curve shifts towards the right, hemoglobin has decreased affinity for oxygen.
If the curve shifts towards the left, hemoglobin has increased affinity for oxygen.
How do I remember the shift in curves?
Remember: Left shifted curve doesn't want to leave oxygen.
