How are the lungs adapted for diffusion
Web16 de mar. de 2024 · Alveoli are tiny, balloon-shaped air sacs located at the end of the bronchioles, the branch-like tubes in the lungs. The alveoli move oxygen and carbon dioxide (CO 2) molecules into and out of your bloodstream. This article discusses the structure and function of the alveoli. WebThe diffusion of oxygen occurs from the alveoli into the blood, whereas the diffusion of carbon dioxide occurs from the blood in the air in the alveoli. The loss of water vapours also occurs from the surface of the alveoli into the lungs. We can observe this condensing while breathing out in cold weather. Inspiration and Expiration
