Researchers from Children's Hospital of Philadelphia (CHOP) have determined what happens at a cellular level as the lung alveolus forms and allows newborns to breathe air. Understanding this process ...

WASHINGTON, Sept. 6, 2022 – 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 ...

The alveoli are microscopic, balloon-like structures in the lungs that play a crucial role in respiration. If they are damaged, they may be able to self-repair, but medical attention is key to ...

Breathing intakes oxygen and expels carbon dioxide, and this gas exchange takes place in the alveoli in the lungs. Alveoli contain type 1 alveolar epithelial cells (AT1), which are involved in the ...

The lungs’ constant pattern of stretching and relaxing that accompanies breathing does more than allow for basic lung functioning—it generates immune responses against invading viruses. Using a human ...

The average person will take more than 600 million breaths over the course of their life. Every breath stretches the lungs’ tissues with each inhale and relaxes them with each exhale. The mere motions ...
