WebTopic: Respiratory System. Gas exchange occurs in the alveoli where oxygen is exchanged with carbon dioxide between the alveoli and the blood in the capillaries. This is driven by the change in partial pressure from the alveoli to the capillaries. In the human body, oxygen is used by cells of the body’s tissues to produce ATP, while carbon ... WebNov 5, 2024 · The alveoli are adapted to make gas exchange in lungs happen easily and efficiently. Here are some features of the alveoli that allow this: they have moist, thin walls (just one cell thick) they have a lot of tiny blood vessels called capillaries. Can alveoli affect lungs? When you exhale, the alveoli shrink, forcing carbon dioxide out of the body.

WebJan 17, 2024 · As the alveoli fill with air during inhalation they expand, and as air leaves the lung with exhalation, the alvoli return to their non-inflated size. The reason for the elasticity of the alveoli is a protein found in the extracellular matrix of the alveoli, called elastin, as well as the surface tension of water molecules on the alveoli themselves. WebPulmonary ventilation provides air to the alveoli for this gas exchange process. At the respiratory membrane, where the alveolar and capillary walls meet, gases move across the membranes, with oxygen entering the bloodstream and carbon dioxide exiting.
