WebThere are three main ways in which the lungs are adapted for efficient gas exchange. These are: the fact that structures in the lungs called alveoli provide a large surface area for gas exchange. Also, the lungs have an excellent blood supply due to a large capillary network, which means a diffusion gradient is always maintained. Finally, the ... 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 … WebAnswer and Explanation: 1. Become a Study.com member to unlock this answer! Create your account. View this answer.
