ANATOMY

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: -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.

Detailed explanation-3: -Your bronchioles are some of the smallest airways in your lungs. Inhaled air passes through tiny ducts from the bronchioles into elastic air sacs (alveoli). The alveoli are surrounded by the alveolar-capillary membrane, which normally prevents liquid in the capillaries from entering the air sacs.

Detailed explanation-4: -Complete answer: Air sacs are the internal compartment filled with air to facilitate internal air. Vertebrates have air sacs present in different body parts & perform various functions. Air sacs provide large surface area for gaseous exchange and increase the respiratory efficiency of the organism.

Detailed explanation-5: -Your trachea divides into your left and right bronchi. The bronchi carry air into your lungs. At the end of the bronchi, the bronchioles carry air to small sacs in your lungs called alveoli. The alveoli perform your body’s gas exchange.
