Question

Which one of the following parameters is not affecting particle deposition in deep lung?​

Answer 1

Explanation:

The magnitude of deposition of inhaled particles in lungs varies with particle parameters (diameter and density), breathing parameters (particle velocity and residence time), and morphometric parameters (branching angle airway radius and gravity angle). Impaction is most effective when air and particle velocities are higher than in the peripheral region of the lungs. However in the alveolar region, particle deposition is mainly guided by diffusion and sedimentation due to smaller velocities and hence longer residence times
