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 ...

Air sacs in the lungs called alveoli are crucial for gas exchange and provide an important barrier against inhaled viruses and bacteria that cause respiratory diseases like flu and tuberculosis (TB).
