How are alveoli adapted for gaseous exchange

WebGas Exchange: Gas exchange refers to the process where organisms absorb a gas from the surrounding environment and releases another. These process occurs both in plants and animals. Plants acquire carbon dioxide for photosynthesis and release oxygen. Animals absorb oxygen essential for cell respiration that produces carbon dioxide, which is ... 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.
