Q
What is 2,3 BPG?
A
Oxygen carrier, carries it from Hb to tissues. Shifts dissociation curve strongly to right
1
Q
What is Henry’s law?
A
When a gas is in contact with the surface of a liquid, the amount of gas that will go into the liquid is proportional to the partial pressure of that gas
2
Q
How is oxygen affinity affected by acidity (increased co2)?
A
It decreases to release oxygen easier
3
Q
What is the Bohr effect
A
Oxygen dissociation curve
4
Q
How does temp and hydrogen affect the Bohr curve?
A
Shift it to the right (decrease oxygen Hb affinity)
5
Q
Normal oxygen pressures
A
Co2 40mmHg
O2 100mmHg
6
Q
How is CO2 transported in blood?
A
Bicarbonate ions via carbonic acid, bound to Hb and plasma proteins and dissolved in plasma
