How many air sacs do birds have?
Birds typically have nine air sacs: two cervical air sacs, two anterior thoracic air sacs, two posterior thoracic air sacs, two abdominal air sacs, and one interclavicular air sac. These air sacs help birds efficiently exchange gases during respiration and aid in maintaining their lightweight body structure for flight.
Are air sacs organs?
Yes they are and they are found in the lungs of birds.
What are birds lungs called?

What adaptations allow birds to get enough oxygen for flight?
1.For birds to be able to take flight or fly high enough and still obtain enough oxygen, the birds have air sacs. 2.(Air sacs are membranaceous receptacles which communicate with the cavities of the respiratory organs passages, and can through be filled with air.) I really hoped this helped, now remember the answer to the question is number 1. The definition of air sacs is number 2.
What do flying dinosaur have hollow bones?
Like birds, Pterodactylus and all other pterosaurs had many tiny air sacs in its bones. The air sacs lowered the density of the pterosaur's bones, thus increasing its weight and making it easier for it to fly.
Breathing mechanism in birds?
Inhaled air passes through the primary bronchus, and most enters the posterior air sacs as well as the lungs. During this passage, air that was in the posterior air sacs moves through the lungs air capillaries so that exchange takes place. During exhalation, the air in the posterior air sacs passes through the lung en route to the external environment. Again exchange goes on during exhalation.
What characteristics is unique to birds?
Presence of five pairs of air sacs , syrinx , feathers and feathered wings , bill or beak are unique characters of birds .
