Question

What would happen to the alveoli if surfactant were not produced? (Module 21.7C) The alveoli would become invaded by pathogens because surfactant was not there to block the pathogens. The alveoli would stiffen because surfactant lubricates the alveoli to they can expand. The alveoli would collapse because of the normally high surface tension of the water coating the alveolar surfaces. The alveoli would collect fluid because surfactant normally soaks up extra fluid and prevents it from accumulating in the lungs. The air exchange across with blood air barrier would improve because surfactant did not block any diffusion.
