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 ...

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 ...

The alveoli are microscopic, balloon-like structures in the lungs that play a crucial role in respiration. If they are damaged, they may be able to self-repair, but medical attention is key to ...

Lung diseases are some of the most common medical conditions in the world. Tens of millions of people have lung disease in the U.S. alone. Smoking, infections, and genes cause most lung diseases. Your ...

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, ...

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 ...

In this work, Katie uses photodegradable hydrogel microparticles to create three dimensional cyst-like structures to mimic the native alveoli of the lung epithelium. Check out the article here!

Part of Biology (Single Science) Cells, organ systems and ecosystems The air that enters the nasal cavity flows down the trachea. The trachea has a number of adaptations: cartilage rings in the walls ...

Many of the organ systems found in animals exhibit highly complex structures, which are essential for their various functions. How such structures develop during embryonic development is a central ...
