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 ...

For the first time, a breathing lung model has been made using cells from only one person. Announced on January 1, the development comes from researchers at the Francis Crick Institute in London and ...

Nicolás Catalán, coauthor of the research, with the three-dimensional model of the human upper respiratory tract. The mask in the background hides the 3D model to simulate any impact of the facial ...

To track the course of inhaled microplastics and their even smaller counterparts, nanoplastics, the study authors constructed a detailed computer model of the human respiratory system from the nose to ...

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).
