Detailed explanation-1: -Tiny air sacs at the end of the bronchioles (tiny branches of air tubes in the lungs).
Detailed explanation-2: -Lung alveoli are found in the acini at the beginning of the respiratory zone. They are located sparsely in the respiratory bronchioles, lining the walls of the alveolar ducts. The alveoli are located in the alveolar sacs of the lungs in the pulmonary lobules of the respiratory zone.
Detailed explanation-3: -The word “alveolus” comes from the Latin word for “little cavity” while the term “alveolar sacs” is derived from the same word and is used to refer to the pouch where the alveoli are located.
Detailed explanation-4: -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.
