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 ...

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).

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 ...

Breathing through your backside may sound like science fiction, but a Japanese clinical trial recently suggested that one day it might help human beings with lungs that can’t get enough oxygen. The ...
