Luftsäcke

Luftsäcke, also known as air sacs, are a series of small, balloon-like structures found in the lungs of birds, reptiles, and some mammals. They are a key feature of the respiratory system in these animals, allowing for efficient gas exchange and oxygenation of the blood. Luftsäcke are connected to the lungs by a network of tiny airways, and they expand and contract with each breath, helping to move air in and out of the lungs. This system is much more efficient than the simple lung structure found in mammals like humans, as it allows for a larger surface area for gas exchange and reduces the energy required for breathing. Luftsäcke are also thought to play a role in vocalization and communication in some species. The exact function and structure of Luftsäcke can vary greatly between different species, but they are a fascinating and important aspect of the respiratory systems of many animals.
