Scientists have created a model alveolar system that mimics the breathing action of the human lung and allows visualization of flow patterns within the alveoli. The chip they designed includes tubes ...

Researchers from Children's Hospital of Philadelphia (CHOP) have determined what happens at a cellular level as the lung alveolus forms and allows newborns to breathe air. Understanding this process ...

The lungs’ constant pattern of stretching and relaxing that accompanies breathing does more than allow for basic lung functioning—it generates immune responses against invading viruses. Using a human ...
