These three features are particularly important to our lungs for efficient gas exchange. Most of them also apply to other exchange surfaces such as the small intestine, body tissues and placenta.

Your lungs are vital for providing your body with fresh oxygen while ridding it of carbon dioxide. This process is called gas exchange. In some individuals, such as those with chronic obstructive ...

oxygen-carbon dioxide exchange (diffusion) pumping blood through your lungs (perfusion) Although tiny, the alveoli are the center of your respiratory system’s gas exchange. The alveoli pick up ...

Gas exchange is the vital function of the lungs. It occurs in the alveoli, where oxygen and carbon dioxide diffuse across the alveolar epithelium and the capillary endothelium surrounding the ...

Perspective from Gerard J. Criner, MD, FACP, FACCP Patients with COPD who underwent autologous transplantation of lung progenitor cells had improved gas exchange capacity, quality of life and ...

Moving gases like this is called gas exchange. The alveoli are adapted to make gas exchange in lungs happen easily and efficiently. Here are some features of the alveoli that allow this ...
