the body which is in motion or rest in air with adjusting the pressure comfortably by their own body parts and travel in air and also changes the path and altitude is called aeronautics
Because streamlined body cuts air and allows birds to move swiftly in air.
When you inahle, air rushes into your lungs because that is the only pathway air is allowed to travel. The body is designed to be air tight and water tight where it needs to be so that no foriegn material can do damage to the rest of the body.
the structure of the trachea is a hole bunch of hulla hoop figures stacked on top of each other its function is to let air travel to the rest of your body
To lower their body density, making it easier to fly.
Your body takes what it needs and then the rest gets exhaled out and goes into the atmosphere.
A downfeather is fluffy feather that traps and keeps air warm against a birds body
The function is to transport air to the rest of the body.
Various objects can travel through air, such as birds, planes, kites, and parachutes. Additionally, wind can carry particles like dust, pollen, and smoke through the air.
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.
Of course. Advanced life forms always need sleep. Some birds rest on branches or in a nest. Others, like the albatross, sleep for a couple hours in the air as they glide.
They connect to air sacks in the body and bones. This makes them more efficient that mammal lungs.
