Nope.
the air sac itself.

embolism
It starts in the nose/mouth, then the air enters the lungs. It then goes into the bronchi ole into the air sac. It is then transported to the circulatory system to produce waste. There is another way which is that the nose/mouth inhales air then it travels down the trachea into the lungs where the waste is produced it then goes to the bronchi then into the circulatory system.
it starts in the mouth and nose cavityoxygon is entered inside our lungs and then what happens is it goes inside the bronchiole into the air sac and transported to the circulatory system and back out into waste or carbon dioxide
The biological term for an air sac is "pneumatic sac," which refers to a structure in the respiratory system of certain animals that aids in breathing by storing or regulating air flow. These structures are commonly found in birds and some reptiles.
the saclike is an ordinary system
ok, think of your lungs as a cluster of grapes hanging upside down. The smallest branches are called bronchioles . At the end of each bronchiole is an "air sac" called alveoli .
First it passes through the tracea, then the bronchus, then alveoli and then finally the air sac.
No, the gastrovascular cavity of Dugesia is not a simple sac. It is a more complex structure that serves both as a digestive chamber and a circulatory system. This cavity has branches that allow for the distribution of nutrients and removal of waste throughout the organism.
An alveolus is a single air-sac, and alveoli are multiple air-sacs.
It is easy for air to pass across the wall of an air sac because the wall is thin.
