WebMar 16, 2024 · The alveoli are the location of gas exchange in the lungs. They have several adaptations that make the diffusion of oxygen and carbon dioxide between the lungs and the blood more efficient. For example, each alveoli is thin-walled and is wrapped in capillaries. This minimises the diffusion distance for the gas molecules. Web- each alveolus is made from single layer of thin flat cells (alveolar epithelium) - this allows for faster rate of diffusion - oxygen diffuses out of alveolar space into blood - CO2 diffuses out from blood capillary into alveolar space - moist alveoli surface supports gas exchange - because the surface is moist it acts as a surfactant (detergent like substance) causes … the marketplace downey ca
Why do the walls of the capillaries and the alveoli need to be thin ...
WebAug 27, 2024 · Alveoli have very thin walls so the diffusion pathway is very short, this means oxygen can diffuse through the wall quickly and easily. Alveoli have a very high … WebOct 16, 2024 · The alveoli and capillaries both have very thin walls, which allow the oxygen to pass from the alveoli to the blood. The capillaries then connect to larger blood … WebSep 20, 2024 · Air passes into the lungs via bronchi, bronchioles, and then into Alveoli. These are individual hollow cavities contained within alveolar sacs (or ducts). Alveoli have very thin walls which permit the exchange of gases Oxygen and Carbon Dioxide. They are surrounded by a network of capillaries, into which the inspired gases pass. tierhilfe argos
