Homework Answers

Answer #1

Multiple factors can influence airway resistance, including the velocity of airflow, the diameter of the airway, and lung volume. These are some of the most significant contributing factor like airway resistance

Surface Tension of the Alveolar Fluid. -Causes alveoli to assume smallest possible diameter. ...

Lung Compliance. -effort required to stretch lungs and thoraric wall. ...

Airway Resistance. -walls of airway offer some resistance to the normal flow of air into and out of the lungs.
