Question

2. Transport of blood gasses: .Oxygen is primarily transported in the blood bound to Carbon dioxide is transported in the blood in the following three ways: (1) as gas ions, (2) bound to , and (3) as (include units) The partial pressure of oxygen in the lungs is approximately The partial pressure of oxygen in the systemic arteries is approximately · The partial pressure of oxygen in the tissues supplied by systemic circulation is approximately . The partial pressure of oxygen in the systemic veins is approximately · The partial pressure of carbon dioxide in the lungs is approximately · The partial pressure of carbon dioxide in the systemic arteries is approximately . The partial pressure of carbon dioxide in the tissues supplied by systemic circulation is approximately · The partial pressure of carbon dioxide in the systemic veins is approximately Write the bicarbonate buffer equation. Increasing the partial pressure of carbon dioxide will pH of the solution. Increasing the partial pressure of oxygen will (increase/ decrease / have little effect on) the Increasing the partial pressure of carbon dioxide will (increase/decrease/have little effect on) the pH of blood plasma. Increasing the hydrogen ion concentration of the solution will Increasing the partial pressure of carbon dioxide will (increase / decrease / have little effect one) blood plasma. Hyperventilation will- (increase / decrease / have little effect on) the pH of blood plasma.

Explanation / Answer

1- Heamoglobin. 1 (i) bicorbonate and hydrogen (ii) proteins, particularly haemoglobin (iii) simple dissolved.

2- 100 mm Hg.

3- 100 mmHg.

4- 40 mmHg.

5- 40 mm Hg.

6- 40 mmHg.

7- 40 mmHg.

8- 45 mmHg.

9- 45 mmHg.

10- Bicarbonate buffer equation-

H2O + CO2 <=> H2CO3 <=> HCO3- + H+

11- Decrease. making it more acidic.

12- unclear phrasing.

13-decrease.

14- increase. because it will cause increase in oxygen and decrease in co2.
