Detailed explanation-1: -Tiny air sacs at the end of the bronchioles (tiny branches of air tubes in the lungs). The alveoli are where the lungs and the blood exchange oxygen and carbon dioxide during the process of breathing in and breathing out.
Detailed explanation-2: -During gas exchange oxygen moves from the lungs to the bloodstream. At the same time carbon dioxide passes from the blood to the lungs. This happens in the lungs between the alveoli and a network of tiny blood vessels called capillaries, which are located in the walls of the alveoli.
Detailed explanation-3: -ALVEOLI are the very small air sacs where the exchange of oxygen and carbon dioxide takes place. CAPILLARIES are blood vessels in the walls of the alveoli.
Detailed explanation-4: -As the alveoli is rich in oxygen and tissues are rich in carbon dioxide(as oxygen is utilized there and carbon dioxide is released as a byproduct ), the gases get exchanged by diffusion along the concentration gradient. So, the gases get interchanged in between the lung and the tissues.
Detailed explanation-5: -The bronchi branch off into smaller bronchi and even smaller tubes called bronchioles (BRAHN-kee-olz). At the end of each bronchiole are tiny air sacs called alveoli. This is the place where the exchange of oxygen and carbon dioxide actually happens.
