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 ...

Lung diseases like emphysema or chronic obstructive pulmonary disease are a leading cause of death worldwide. With the advent of COVID-19, these diseases have only become more prevalent. Despite the ...

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 ...

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 ...

A novel 3D-cell culture method enables the rapid production of genetically identical ‘lung buds’ for the investigation of respiratory diseases, providing new insights into the pathogenesis of COVID-19 ...

Researchers at Texas Biomedical Research Institute report they have created a new cell culture model for human alveolar macrophages in the lab. The model was developed to improve research for lung ...
