What best explains the role of surfactant in Respiratory Distress Syndrome?O Smooth muscle surrounding bronchi constrict and restrict air flow when surfactant is not presentO Underdeveloped Type 1 cells prevent proper gas exchange across the respiratory membraneO Type 2 cells overproducing surfactant cause the alveoli to fill with fluidO A lack of surfactant from goblet cells allows dust particles to get into the alveoliO Insufficient surfactant makes it challenging to inflate the alveoliQuestion 4Which of the following structures is NOT lined by a pseudostratified ciliated columnar epithelium?O TracheaO LaryngopharynxO Nasal cavityO NasopharynxO Paranasal sinuses

Ms. Y diver wanted to do some underwater exploration. She did not want to buy expensive scuba equipment, however. Instead, she bought a long hose and an inner tube. She attached one end of the hose to the inner tube so thathe end was always out of the water, and she inserted the other end of the hose in her mouth and went diving. What happened to her alveolar ventilation and why? How can she compensate for this change? How does diving affect thoracic compliance and the work of ventilation?
