What these tiny sacs in the lungs do and conditions that can affect them Medically reviewed by Susan Russell, MD Alveoli are ...

The condition causes substances such as fats and proteins to accumulate in the alveoli, the ‘air sacs’ of the lung, where oxygen and carbon dioxide enter and exit the blood stream. This ...

It travels down the trachea – or windpipe – into one of two bronchi and into bronchioles before entering one of millions of alveoli, where gaseous exchange takes place. When we breathe out ...

The abnormal accumulation of extravascular fluid, pulmonary edema settles in the lung interstitium and alveoli. There, it ...

A new study from Tulane University suggests that repeated collapse and reopening of tiny alveoli-air sacs in the lungs essential for breathing-during mechanical ventilation may cause microscopic ...

The research, published in Nature Communications, shows a new set of molecular markers that distinguish gradual stages of damage to alveoli in the lungs. The work opens the door to further ...
