Atelectasis (pronounced a-teh-LEK-tuh-sis) is a lung condition that happens when your airways or the tiny sacs at the end of them don’t expand the way they should when you breathe. Because of this, a ...

Bibasilar atelectasis is when there is a collapse in the bottom part of both lungs. It can cause symptoms such as shortness of breath, coughing, wheezing, and more. Atelectasis is a partial or total ...

Discover how air pollution impacts children's lung development, leading to chronic inflammation and long-term health concerns.

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 ...

Using animal models, University of Alberta researchers have taken what they say is the first important step towards treatment for lung disease in premature babies, in effect, growing new blood vessels ...

Specialized lung cells appear in the developing fetus much earlier than scientists previously thought. A new animal study (“Early lineage specification defines alveolar epithelial ontogeny in the ...

Lung damage causes proliferation of P63-expressing cells in bronchioles, migration to damaged tissue, and regeneration of alveoli. Scientists have identified a subset of stem cells in rodents and in ...

The biomimetic lung unit model, comprising a biomimetic membrane, vascular cells, and pulmonary cells, can mimic respiration and cultivate cells at the air-liquid interface. The biomimetic membrane, ...

The most important lung function is to take oxygen from the environment and transfer it to the bloodstream. Lung function tests can show how well the lungs carry out this task. The left and right ...

Scientists have created a model alveolar system that mimics the breathing action of the human lung and allows visualization of flow patterns within the alveoli. The chip they designed includes tubes ...
