This elaborately involuted tissue of air sacs and blood vessels serves to exchange gases between the air and the blood. In man the total area of the membrane between the two systems is 70 square ...

Lungs are spongy, filled with tiny air sacs which give them a spongy texture. And our lungs are really large in surface area.

Your lungs contain approximately 600 million alveoli, the tiny air sacs responsible for exchanging oxygen and carbon dioxide with your bloodstream. Under normal breathing patterns, many of these ...

Smoking damages the airways, air sacs (alveoli) in the lungs, and cilia, which are tiny hair-like structures that prevent dirt and mucus from entering your lungs. Withdrawal from tobacco products ...

While ILDs are a diverse group of lung diseases, they all affect the interstitial space (interstitium)—a network of blood vessels and connective tissues in and surrounding the air sacs of the ...

The study suggests that repeated collapse and reopening of tiny alveoli -- air sacs in the lungs essential for breathing -- during mechanical ventilation may cause microscopic tissue damage ...

Published in the Proceedings of the National Academy of Sciences, the study sheds light on ventilator-induced lung injury, a complication that gained increased attention during the COVID-19 ...
