These three features are particularly important to our lungs for efficient gas exchange. Most of them also apply to other exchange surfaces such as the small intestine, body tissues and placenta.

Moving gases like this is called gas exchange. As the blood moves through ... is also lost from the surface of the alveoli into the lungs - we can see this condensing when we breathe out on ...

Survival rates for idiopathic pulmonary fibrosis are worse than all solid cancers except for lung and pancreatic cancer. | ...

This led to a “new” definition of BPD in which impairment of alveolar formation is the prominent feature, leading to long-term global reduction in alveolar number and gas-exchange surface area ...

A new form of diagnostic imaging is changing how doctors see and treat lung conditions like cystic fibrosis. For as long as ...

It’s possible to catch a cold or get the flu at any time of year. But the chances of becoming sick increase during cold and ...

This cancer originates in the epithelial cells that line the lung’s alveoli, the tiny sacs responsible for gas exchange between the bloodstream and inhaled air. Most lung adenocarcinoma studies ...

Alveolar cells, which are epithelial cells crucial for gas exchange inside the lung, can be grouped into two cell types. Type ...

In general, the capacity of the pulmonary system far exceeds the demands required for ventilation and gas exchange during exercise. Endurance training induces large and significant adaptations within ...

The lungs consist of thin-walled air sacs called alveoli. Gas exchange occurs between alveolar air and capillaries within thin layers of interstitial tissue, which are micrometers thick.
