Which of the properties a respiratory surface must have?
a) Non-moist
b) Thick and hard
c) None of these
d) Small surface area
6.
Why a respiratory surface must have large surface area?
a) Respiratory surface must have small surface area
b) So that limited amount of gases can be exchanged
c) So that no amount of gases can be exchanged
d) So that sufficient amount of gases can be exchanged
7.
Why a respiratory surface must have small surface area?
a) Respiratory surface must have large surface area+So that sufficient amount of gases can be exchanged
