it contains less Oxygen

it is present deep in lungs

16- Pulmonary ventilation is

*

Directly related

inversely related

not related

*

Formation of haemoglobonic acid

formation of bicarbonated

to keep electrostatic neutrality of RBC membrane

to transport CO2

19- Haldane effect refers to

*

Increased C02 uptake to minimize Co2 tension

Increased 02 tension

decreased CO2 tension

Decreases O2 tension

20- Bohr effect shifts the O2 hb dissociation curve to the right.

*

to promote the oxygenation of Hb in lungs

To increase O2 concentration

to decrease CO2 concentration

to decrease the pH of the blood

21- advantage of double bohr effect is

*

reciprocal exchange of oxygen for CO2

More Oxygenated of foetal blood

more removal of CO2

All of these

22- At high altitude the number of RBC increases

*

To trap O2 from rarefied air having low PO2

To adapt with the oxygen deficiency

to remove more CO2
