Reptile lungs do not contain alveoli in the same way that mammalian lungs do. Instead, reptilian lungs are typically structured with a series of air sacs or chambers that facilitate gas exchange. Some reptiles have a more complex lung structure with infoldings to increase surface area, but they lack the alveolar system found in mammals. As a result, while they can effectively exchange gases, their respiratory system is different from that of mammals.

The lungs contain alveoli, bronchioles, and bronchi. Alveoli are tiny air sacs where oxygen is exchanged for carbon dioxide in the blood. Bronchioles are small airways that branch from bronchi, which are larger airways that lead to the lungs.
The lungs contain air sacs called alveoli which are surrounded by blood capillaries to allow gaseous exchange.
Each lung houses about 300-400 million alveoli.
Alveoli alveoli - air sacs in your lungs
The lungs are comprised of alveoli.
Human respiratory system contain wind pipe or trachea, bronchus, bronchi, alveoli with blood capillaries. Lungs have air sacs or alveoli which are surrounded by capillaries which oxygenate, de-oxygenated blood.
The lungs contain the most alveoli in the human body. Alveoli are tiny air sacs in the lungs where gas exchange occurs, allowing oxygen to enter the bloodstream and carbon dioxide to be removed. The large surface area of alveoli is essential for efficient gas exchange during respiration.
