How are the lungs adapted
WebThe Lungs –adapted to make gas exchange more efficient. The lungs are made up of alveoli. Alveoli –are tiny air sacs, which give the lungs a very large surface area with a good blood supply and short diffusion distances. The lungs are ventilated to maintain steep diffusion gradients. WebThe alveoli are small, round, or balloon-like structures at the ends of the bronchioles that increase surface area and maximize gas exchange in the lungs. The alveoli are sac with a diameter of about 0.2-0.5 mm. These alveoli are located in the lungs at the end of the airways. Alveolar structure can be associated with the appearance of ...

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. WebRespiration refers to a process in which the energy is released from the glucose so that the life processes can continue. There are two types of respiration: Aerobic respiration: It needs oxygen. Anaerobic respiration: It does not need oxygen. Our respiratory system is adapted to carry the exchange of gases efficiently.
