Artificial breathing system reveals alveoli function in lungs

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 arranged like the structure of a bifurcation point in the bronchial network. The upper layer of the chip is made of a flexible polymer molded into small tubes that mimic the alveolar structure. The lower layer is glass, which allows the authors to visualize fluid flow through the tubes.
