Gas Transport

Question 1

right shift of O2 dissociation curve?

Answer 1

increased temperature
increased P CO2
decreased pH
increased DPG

will offload concentration easier

Question 2

hemoglobin saturation?

Answer 2

can be almost completely saturated until PO2 below 60 mmHg

Question 3

bohr effect?

Answer 3

shift in O2 dissociation with change in pH

to left - increased pH
to right - decreased pH

Question 4

Hg binding and CO effects?

Answer 4

shifts curve to left ** hangs on longer
and decreases O2 concentration possibly held by the Hg

increases O2 affinity of hemoglobin

• will hold on to it longer
• CO also takes up spaces that O2 would be binding to normally

Question 5

H+ and CO2 and vasoconstriction?

Answer 5

yes

Question 6

carbonic anhydrase

Answer 6

H2O + CO2 > bicarbonate

Question 7

majority of CO2 in blood?

Answer 7

bicarbonate

Question 8

haldane effect

Answer 8

decreased oxygenation of blood increases its capacity to carry carbon dioxide

helps move carbon dioxide to lungs

Question 9

CO2 vs O2 dissociation curves?

Answer 9

CO2 more linear

easily eliminated
