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 ...

A discovery about how severe COVID-19 damages lung cells suggests that an existing drug could treat lingering respiratory problems not just from COVID but influenza and other respiratory infections.

A person’s windpipe splits into two bronchi, one for each lung. The bronchi then divide into smaller bronchi, which split into bronchioles. These lead to tiny air sacs known as alveoli.

diseases that often cause thick mucus buildup along the lungs’ air sacs. Pulmonary vascular lung diseases, which include pulmonary hypertension and pulmonary embolism, concern the organ’s ...

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 ...
