Oxyhaemoglobin dissociation curve Flashcards
1
Q
Association
A
when O2 combines with haemoglobin through diffusion at lungs
2
Q
Saturated
A
amount of O2 combined with haemoglobin, expressed as a % depends on PPO2
3
Q
Dissociation
A
when O2 releases from haemoglobin through diffusion at the muscles
4
Q
Oxyhaemoglobin dissociation curve
A
relationship between PPO2 & % saturation of haemoglobin
5
Q
Haemoglobin
A
carries O2 in the blood as oxyhaemoglobin from lungs to the muscles

7
Q
AT MUSCLES haemoglobin ….% with O2
A
75%
8
Q
AT REST ….% of O2 dissociated with haemoglobin & diffuses into muscles
A
25%
