How are the lungs adapted for diffusion
WebThe alveoli are covered by a rich blood supply of capillaries- this provides a diffusion gradient for oxygen to move into the blood and carbon dioxide to move into the lungs.The alveoli are also highly folded, meaning there is a high surface area: volume ratio for gas exchange.Finally, the alveolar walls are only one cell thick, so the gases can … Web30 de nov. de 2024 · The lungs are well supplied with blood due to lots of capillaries covering the alveoli, constantly maintaining a large diffusion gradient, air is able to …
How are the lungs adapted for diffusion
Did you know?
WebOxygen is absorped into the blood by the process of diffusion. A large surface area, short diffusion pathway (the distance the oxygen has to travel through) and large concentration gradient increases the rate of diffusion and therefore oxygen absorption. The lungs are made up of many tiny air sacs called alveoli. Web16 de mai. de 2024 · Some adaptations are related to the alveoli, exercise, surface area, and ventilation. 1. Alveoli The alveoli are the location of gas exchange in the lungs. They …
