organs which help to decrease the weight of the body during flying in aves?
Answers
Answer:
Flying birds have:
lightweight, smooth feathers – this reduces the forces of weight and drag
a beak, instead of heavy, bony jaws and teeth – this reduces the force of weight
an enlarged breastbone called a sternum for flight muscle attachment – this helps with the force of thrust
light bones – a bird’s bones are basically hollow with air sacs and thin, tiny cross pieces to make bones stronger – this reduces the force of weight
a rigid skeleton to provide firm attachments for powerful flight muscles – this helps with the force of thrust
a streamlined body – this helps reduce the force of drag
wings – these enable the force of lift.
