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 ...

Alveoli are the basic functional units of the human respiratory system, acting as tiny air sacs that exchange gases. Air inhaled through the mouth and nose flows into the lungs through the branched ...

Lungs are highly vulnerable to injury and infection due to continuous exposure to inhaled environmental pathogens and particles. As a result, respiratory diseases are a leading cause of disability and ...

With recent studies having established the presence of nano and microplastic particles in the respiratory systems of both human and bird populations, new research has modeled what happens when people ...
