Oxygen dissociation Flashcards
1
Q
Define oxygen dissociation
A
the tendency of oxygen to leave the haemoglobin
2
Q
In which blood vessel is haemoglobin saturation of oxygen at its highest
A
Arteries
3
Q
What is the rightward shift of the oxygen dissociation curve caled
A
The Bohr shift
4
Q
Name the 4 causes of the Bohr shift
A
-lower blood PH
-prescence of CO2
-production of lactic acid
-increased body temperature
5
Q
The Bohr means that oxygen is more likely to … from haemoglobin
Fill in the blank
A
Dissociate
6
Q
What does the Bohr shift mean for oxygen delivery during exercise
A
Oxygen delivery to the muscles is greater as there is a decreased amount of oxygen saturation with haemoglobin in venous blood
