Do bats have air sacs?
Birds and bats are the only extant vertebrate taxa that have achieved flight. The lung/air sac system of birds is not therefore a prescriptive morphology for flight: the essence of its design can be found in the evolution of the reptilian lung, the immediate progenitor stock from which birds arose.
What is the breathing organ of bat?
They have a rib cage that hold the lungs and have systems, like the bronchioles, to diffuse oxygen to the rest of their body. They also have a trachea to direct the air into the lungs.
Are bats the only Chiroptera?
Bats are mammals of the order Chiroptera. With their forelimbs adapted as wings, they are the only mammals capable of true and sustained flight….Bat.

What are air sacs?
air sac, any of the air-filled extensions of the breathing apparatus of many animals. Air sacs are found as tiny sacs off the larger breathing tubes (tracheae) of insects, as extensions of the lungs in birds, and as end organs in the lungs of certain other vertebrates.
Does a lizard have an air sac?
A lizard captures oxygen from air both when inhaling and exhaling—a feat normally associated with birds. Not birds, which store some of the air they inhale in specialized sacs. When they exhale oxygen is extracted from this air.
Where are Chiroptera found?
Typical habitats include temperate and tropical forests, deserts, open fields, agricultural areas, and in suburban and urban environments. Many bats forage near freshwater streams, lakes and ponds, preying on insects as they emerge from the water.
What is the order of Chiroptera?
Therapsid

Where are air sacs found?
lungs
Air sacs are found as tiny sacs off the larger breathing tubes (tracheae) of insects, as extensions of the lungs in birds, and as end organs in the lungs of certain other vertebrates. They serve to increase respiratory efficiency by providing a large surface area for gas exchange. See also pulmonary alveolus.
What are air sacs made of?
The air sacs are thin-walled structures composed of simple squamous epithelium covering a thin layer of connective tissue with very few blood vessels (McLelland, 1989b).
