Gasous Exchange

Question 1

Gaseous exchange

Answer 1

The exchange of CO2 and O2 within the alveoli and capillaries

Starts low O2, high CO2
Ends high O2, low CO2

Question 2

Diffusion

Answer 2

The capillary starts with High CO2, Low O2
The alveoli starts with Low Co2, High O2

The capillary ends with Low Co2, High O2
The alveoli ends with High Co2, Low O2

The gasses can diffuse as the layers of alveoli and capillary is 1 cell

Question 3

Transport O2

Answer 3

97% Hemoglobin

3% Dissolved in plasma

Question 4

Transport CO2

Answer 4

22% carbaminohemoglobin
8% dissolved in blood pressure
70% CO2 +H2O = H2CO3 = HCO3 + H+ (hydrogen ion)

Question 5

Acidity

Answer 5

Carbon dioxide is more acidic than oxygen as there is more carbon than oxygen
