Gas exchange occurs Gas exchange takes place at the surface of the fluid (the 'fluid/gas interface') at the ends of the finer tubes - tracheoles - where oxygen dissolves in the fluid and CO 2 leaves it. The fluid is in contact with a thin layer of liquid covering the internal muscles etc. and dissolved oxygen is passed to them by diffusion. Gas exchange is the process of swapping one gas for another. It occurs in the alveoli of the lungs. Oxygen diffuses into the capillaries from the air in the alveoli and carbon dioxide diffuses out of the capillaries and into the air in the alveoli.

Definition av alveolar dead space. That volume of air in the ''alveoli'of the lung which does not partake in gas exchange.

This means that net diffusion occurs into the alveoli from capillaries. Alveoli have a large surface area because there are lots of them. 9. You breathe in oxygen rich air.

Their shape provides a greater Alveoli are the air sacs at the end of the respiratory tree of the lungs and are vital to respiration. Learn about their structure and common diseases. 15 Mar 2016 In alveolar lungs as occur in mammals, gas exchange occurs by air flowing in through the airways and mixing with air contained in the alveolar The tissue interface between the air in the alveoli and the capillary blood in the lungs is extremely thin (~0.1–0.5 μm) and is well adapted for the passage of gases. The partial pressure of carbon dioxide in the capillaries is much higher than that in the alveoli. This means that net diffusion occurs into the alveoli from capillaries.
