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.

They provide an extra gas exchange surface. Bird and fish respiratory systems are similar in that both: function by means of unidirectional flow of the environmental medium over the gas exchange membranes.
Why do birds have so many air sacs?
Many birds have hollow, lightweight skeletons and specially-designed wings to help them stay aloft. ... The respiratory system of birds facilitates efficient exchange of carbon dioxide and oxygen by using air sacs to maintain a continuous unidirectional airflow through the lungs.
Do air sacs help birds fly?
They have special air sacs in addition to their lungs, with hollow bones that allow these gasses to flow around the body more easily. This means that one bird breath goes further and does more work than one mammal breath.
What is one way in which air sacs are helpful to birds?
What is one way in which air sacs are helpful to birds? Air sacs allow the bird to obtain fresh oxygen both when inhaling and exhaling, providing extra oxygen needed for flight. They are also the primary way a bird cools its body, allowing more air to enter the body and warm air to leave.
