Bohr shift is when the dissociation curve for oxygen shifts to the right as a result of carbon dioxide levels. It shifts to the right as when carbon dioxide is present haemoglobin has a lower affinity for oxygen so it dissociates much more easily. This is useful as in respiring tissues carbon dioxide is produced so more oxygen dissociates which is vital as the tissue will need more oxygen.

When carbon dioxide is broken down the hydrogen carbonate ions diffuse out of the erythrocyte but as it has a -1 charge a Cl- ion is used to balance the charge between the erythrocyte and the blood plasma which is chloride shift
