We need to get oxygen from the air into the blood, and we need to remove waste carbon dioxide from the blood into the air. Moving gases like this is called gas exchange. As the blood moves through the ...

Alveoli are tiny air sacs in your lungs that take up the oxygen you breathe in and keep your body going. Although they’re microscopic, alveoli are the workhorses of your respiratory system. People ...

Your lungs are vital for providing your body with fresh oxygen while ridding it of carbon dioxide. This process is called gas exchange. In some individuals, such as those with chronic obstructive ...

Scientists from Imperial College London have successfully directed mouse stem cells to turn into the type of cells needed for gas exchange in lungs, bringing the prospect of being able to regenerate ...

The novel agent molgramostim improved pulmonary gas exchange in autoimmune pulmonary alveolar proteinosis, a randomized trial showed. In this rare condition, surfactant builds up in the alveoli as ...

The respiratory system is the system of organs that allow the body to take in oxygen and expel carbon dioxide, this process is known as gaseous exchange. We generally breathe between 12 and 20 times a ...

We know ozone is bad for our lungs – the increased risk of developing diseases such as asthma was one of the reasons people wore face masks during January’s record-breaking smog in China. But exactly ...

The cells in the body need oxygen to release energy from food efficiently by carrying out aerobic respiration. A waste product of aerobic respiration is carbon dioxide. The layer of moisture in the ...

Inhaled recombinant human granulocyte-macrophage colony-stimulating factor (GM-CSF) needed to clear lung surfactant improved lung gas exchange in the rare autoimmune condition pulmonary alveolar ...
