BRAINCAKEEffect of Carbon Dioxide
The haemoglobin dissociation curve is further to the right in the presence of carbon dioxide. The greater the concentration of carbon dioxide, the lower the affinity for oxygen. This is known as the Bohr effect.
At the surface of the lungs there is a high partial pressure of oxygen and the concentration of carbon dioxide is low. The affinity of haemoglobin for oxygen is higher and oxygen is loaded onto the haemoglobin.
