Question
Human Anatomy and Physiology Question on The respiratory system
To determine the effect of breath holding on the deposition of particles, the sedimentation efficiency, S, is defined as
A
S = (Distance the particle falls during breath holding) (Mean regional airway diameter)
B
S = (Distance the particle falls during breath holding) × (Half the mean regional airway diameter)
C
S = (Distance the particle falls during breath holding) + (Twice mean regional airway diameter)
D
S = (Distance the particle falls during breath holding) - (Mean regional airway diameter)
Answer
S = (Distance the particle falls during breath holding) (Mean regional airway diameter)
Explanation
Solution
The correct option is (A): S = (Distance the particle falls during breath holding) (Mean regional airway diameter)
