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 ...

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 ...

Researchers at the Francis Crick Institute and AlveoliX have developed the first human lung-on-chip model using stem cells taken from only one person. These chips simulate breathing motions and lung ...

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 ...

This 1930s educational film provides a detailed exploration of the respiratory and excretory systems, combining live-action demonstrations, animations, and intertitles to illustrate human anatomy and ...
