Answer #1

Option C-. an increase in airflow in to the alveoli.

Surfactants are compounds that lower the surface tension .

The function of surfactant in the Alveoli is to lower the surface tension at the air/liquid interface within the alveoli .

In Normal case--Pulmonary surfuctant makes Reinflation of alveoli after expiration more easier.

Insufficiency or reduction of  pulmonary surfactant in the alveoli can lead to----- atelectasis (collapse of the lung ).

You are designing an air pressure vessel with a corrosion resistant interior coating. Will the surface energy of the interior wall increase or decrease when pressurized? Use drawings to guide your answer. I believe the answer is that the surface energy will decrease. However, in the instance we learned in class we were looking at a liquid and particles. Therefore, my logic was that the corrosion resistant material would create a lower affinity for the particles in which case absorption...
