WebAdaptations of exchange surfaces. For respiration, organisms need to take oxygen into their bodies and remove carbon dioxide.These gases diffuse across exchange surfaces, such as the lungs, so exchange surfaces are adapted to make diffusion as efficient as possible. Most gas exchange surfaces are extremely thin (sometimes just one cell … WebThe Lungs. Most mammalian lungs have the same basic structure.The Trachea (windpipe) leads from the mouth and nose and splits into the Bronchi which in turn split into the Bronchioles which lead to the Alveoli (air sacs) where gaseous exchange occurs..

WebAlveoli are highly adapted for gas exchange by diffusion between air in the lungs, and blood in the capillaries. They are folded in order to maximise the surface area to volume ratio. This allows more gas exchange to take place. The alveoli wall linings are moist, allowing oxygen and carbon dioxide to dissolve easily. Web3) Ventilation of the lungs brings oxygen into the alveoli and removes carbon dioxide. The circulation of blood through capillaries is constantly bringing in blood with low oxygen. This maintains a steep concentration gradient across the alveolar wall for a faster rate of diffusion for oxygen and carbon dioxide. Answered by • Biology tutor.
