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 ...

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 ...

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 ...

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 ...

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 lungs through the branched ...

An alveolus (plural: alveoli), is an anatomical structure that has the form of a hollow cavity. In the lung, the pulmonary alveoli are spherical outcroppings of the respiratory bronchioles and are the ...

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 ...

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 ...

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, ...

What Is the Respiratory System? The respiratory system is the organs and other parts of your body involved in breathing, when you exchange oxygen and carbon dioxide. All the cells in your body need ...
