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 ...

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 ...

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 ...

When Laura Sadofsky, PhD, a senior lecturer in Respiratory Medicine at the University of Hull, Hull, England, began looking at the effects of microplastic exposure on respiratory health 6 years ago, ...
