Question 8 of 21

1

Diffusion of Gases is influenced by

Select one or more of the following:

  • Laws of diffusion

  • Measurement of diffusing capacity

Explanation

Question 9 of 21

1

Fill the blank space to complete the text.

Diffusion through tissue's is described by 's Law

Explanation

Question 10 of 21

1

Select from the dropdown lists to complete the text.

For diffusion through a tissue sheet, the amount of a gas transferred is proportional to ( Area available for diffusion (A), Diffusion constant (D), Difference in partial pressure (P1-P2), thickness of the tissue (T) ), ( Diffusion constant (D), Difference in partial pressure (P1-P2), thickness of the tissue (T) ), ( Difference in partial pressure (P1‐P2), Diffusion constant (D), Area available for diffusion (A), thickness of the tissue (T) ) and inversely proportional to ( thickness of the tissue (T), Area available for diffusion (A), Diffusion constant (D), Difference in partial pressure (P1‐P2) )

Explanation

Question 11 of 21

1

Fill the blank spaces to complete the text.

Diffusion constant is to the gas solubility (Sol) and to square root of its molecular weight.

Explanation

Select one of the following:

  • CO2

  • O2

Explanation

  • Co

  • N2O

  • O2

  • CO2

Explanation

Question 14 of 21

1

Fill the blank space to complete the text.

Transfer of CO is . Amount taken up depends on how
much CO is available

Explanation

Question 15 of 21

1

Fill the blank space to complete the text.

N2O transfer is . Amount taken up depends on how
much blood can flow through

Explanation

Explanation

Question 21 of 21

1

Fill the blank space to complete the text.

At rest, the PO2 of the blood virtually reaches that of the alveolar gas after about
1/3 of its time in the capillary so O2 transfer is really only limited by
