What is the difference between bird bones and human bones? Have you ever wondered how the shape of a bone can affect the function? Did you think it did not make a difference? If so then you are wrong. The shape of bird bones and human bones are very important because humans and birds are very different and the bones have to work as an advantage for those differences, For Example:
A bird’s bone is hollow for a lot of reasons, such as:
The bird needs to have a limited amount of weight so it can fly, if the bone wasn’t hollow it wouldn’t be able to fly. Flying benefits the bird for many different reasons. One of them is that they don’t have to worry about the land predators as much as the air predators. Smaller birds fly away fast and attack the predator if it is going for the nest.
The bird bone is hollow but human bones are not. The outside layer is dense, a tough outer layer. The next layer is spongy bone and after that is marrow. That combination makes human bones. Our bones aren’t only for holding us up though, our bones do many things. Our bones are used for storage of blood cells, and fatty acids. Our bones also help us move. And they help protect some of our internal organs, like our ribs help protect our heart.
