Researchers have uncovered changes in the cellular response throughout lung damage caused by SARS-CoV-2—the virus behind ...

The bronchi in the lungs split into smaller and smaller tubes called bronchioles. These end in microscopic air sacs called alveoli. The process of ventilation as a series of changes in pressure ...

Carbon dioxide diffuses from the blood into the alveoli. These three features are particularly important to our lungs for efficient gas exchange. Most of them also apply to other exchange surfaces ...

A new study sheds light on ventilator-induced lung injury, a complication that gained increased attention during the COVID-19 pandemic, which led to a surge in patients requiring mechanical ...
