The purpose of the lung is gas exchange. In practice, the lung is often approximated as the size of a tennis court that is exchanging oxygen and carbon dioxide with the bloodstream in our bodies. This ...

Researchers at the Perelman School of Medicine at the University of Pennsylvania have produced a detailed molecular atlas of lung development, which is expected to be a fundamental reference in ...

The successful engineering of synthetic organs has long been a goal in biomedical research, but many organs are incredibly complex structures that contain a variety of different cell types, which then ...

A fetus needs oxygen long before its lungs work and it’s exposed to the air. ... can bind to one oxygen molecule each. Image generated from PBD ID 1C7B by Julie Pollock, CC BY-ND.

Red blood cells contain a molecule that gives them their distinctive color. ... To return to human blood, the iron in hemoglobin binds oxygen in the lungs as we inhale air.

Biologists have revealed a mechanism by which bacterial cells in crowded, oxygen-deprived environments access oxygen for energy production, ensuring survival of the cell. The finding could explain ...

The reason is that your nasal cavities produce the molecule nitric oxide, which chemists abbreviate NO, that increases blood flow through the lungs and boosts oxygen levels in the blood.
