Abstract
Respiration provides oxygen (O2) and removes carbon dioxide (CO2) for the body. An extraordinary anatomic arrangement of functional units (the alveoli) delimited by extra-thin walls (epithelium and endothelium) creates the interface for gas exchange between air and blood. Repetitive expansion and collapse of the chest wall facilitates movement of gas in and out of the lungs. This review focuses on the mechanical events that regulate the exchange of O2 and CO2 between the body and the outside environment.
