In an evolutionary perspective, the size of primitive multi-cellular species was necessarily limited by nutrients' diffusion speed ... that the structure of the alveolar system is indeed optimal ...

These air sacs move oxygen into your blood. Alveolar walls contain surfactant. This is a substance made of fats, proteins, and other substances. This surfactant helps the alveolar walls stay open ...

moving air in and out of your lungs (ventilation) oxygen-carbon dioxide exchange (diffusion ... at the end of each bronchiole is a small duct (alveolar duct) that connects to a cluster of ...

Dr. Cindy McEvoy will present “Increased Alveolar Volume and Lung Diffusion Capacity in Former Preterm Infants Randomized to Two Extra Weeks of Continuous Positive Airway Pressure (CPAP) ...

Alveolar ventilation is normally between four ... If the response to provided oxygen is poor, it suggests the existence of a severe diffusion-perfusion abnormality or a shunt.

Background—Pulmonary diffusing capacity for carbon monoxide (Dlco), alveolar capillary membrane diffusing capacity (Dm), and pulmonary capillary blood volume (Vc) are all significantly reduced after ...

The alveolar bone, commonly known as the jaw bone, is a unique bone tissue that houses and supports our teeth. Their results, published online on Jan. 25 in the Journal of Clinical Investigation ...
