Lecture 8 - Diffuse Gas Exchange

Question 1

Partial pressure definition?

Answer 1

pressure required to prevent a gas from diffusing out of its solution`

Question 2

solubility definition and equation?

Answer 2

amount of gas dissolved per unit volume per unit of partial pressure (content of solution/partial pressure of gas)

Question 3

Diffusive capacity of lung equation?

Answer 3

diffuse constant of gas x solubility of gas x (area/diameter)

Question 4

Use of carbon monoxide in experiment?

Answer 4

similar solubility to oxygen, great avidity to Hb
