Transport of Gases

The figure given below shows a small part of human lung where exchange of gases takes place. In which one of the options given below, the one part A, B, C or D is correctly identified along with its function?

​

Carbonic anhydrase occurs in

The carbon dioxide is transported via blood to lungs as:

Although much CO₂ is carried in blood, bloods does not become acidic because

Oxygen dissociation curve of haemoglobin is

Blood analysis of a patient reveals an unusually high quantity of carboxyhaemoglobin content. Which of the following conclusions is most likely to be correct?

"The patient has been inhaling polluted air containing unusually high content of ___________________."

The process of migration of chloride ions from the plasma to RBC and that of carbonate ions from RBC to plasma is
 

The exchange of gases in the alveoli of the lungs takes place during respiration. Identify the labeling a-e.

Which among the given ones is the most probable reason for higher diffusion rate of CO₂ than O₂ through diffusion membrane, for per unit difference in partial pressure?

Which of these is correct regarding $D$, $E$ and $F$ areas in the graph?

Study the following statements

I. Effect of CO₂ and H⁺ on the oxygen affinity of haemoglobin is termed Bohr effect.
II. Formation of carbonic acid is faster in plasma than RBC due to the carbonic anhydrase.
III. Decrease in pH, increase in CO₂ and temperature shifts oxyhaemoglobin dissociation curve to the left side.
IV. Exchange of chloride and bicarbonate ions between RBC and plasma is called Hamburger's phenomenon.

Correct statements are:

If ${\mathrm{pCO}}_2$ is high and ${\mathrm{pO}}_2$ is low:

Blood transport of ${\mathrm{CO}}_2$ occurs in three forms. The correct percentages of ${\mathrm{CO}}_2$ in these forms are

Which of the following is not true?
