pneumatic bones reduces the corporal density of animal faciliating flights
Birds have pneumatic bones.
Birds have some bones in their bodies that are "hollow." These are called pneumatic bones, and they help birds breathe when they are in flight. The bones of the pelvic girdle, some ribs, the humeru,s and the femur all are pneumatic.
The phylum that has the adaptive feature of pneumatic bones is Chordata. Pneumatic bones are lightweight structures filled with air that help reduce the weight of the skeleton, making it easier for organisms to fly or swim, such as in birds.
Bone marrow is absent in birds, because they have pneumatic bones
It's the same thing as a hollow bone. That's one of the characteristics birds posse than enables them to fly (if their bones had the same weight as ours, they wouldn't be able to lift). Some dinosaurs had the same type of bones. Hope it helped.
The pneumatic bones are where the air sacs, part of the respiratory system, connect with some of the longer bones. These bones are hollow to help with flight.
birds have wings and air-filled spongy pneumatic bones which helps them to adapt them to aerial life.its to fly about in sky

Bird bones are lightweight due to the presence of air cavities within them, known as pneumatic bones. These hollow spaces reduce the overall density of the bones while maintaining their strength, allowing birds to fly more efficiently. Additionally, the arrangement of bone structure in birds is highly optimized for strength and minimal weight, contributing to their lightweight nature.

No, they do not.
