Birds are very lightweight boned animals. :)
Trabecular bone.
The spongy bone is strong but lightweight.
Death is a part of all life
spongy bone. And it is usually at the end of a bone next to the joint
A lightweight bone filled with spaces is likely to be a cancellous or spongy bone. This type of bone tissue has a honeycomb-like structure with many small cavities that are filled with bone marrow. Cancellous bone is found at the ends of long bones and in the interior of flat bones.
Spongy
Trabecular bone, also known as cancellous or spongy bone, is a lightweight porous bone that consists of a network of interconnected struts and girders. It is found at the ends of long bones and within the vertebrae, providing structural support while allowing for flexibility and shock absorption.
Bones are made up of a matrix of collagen fibers and calcium crystals, which provide both flexibility and strength. The hollow structure of bones, filled with marrow, also contributes to their lightweight nature. Additionally, the arrangement of compact and spongy bone tissues distributes forces and enhances the bone's ability to withstand compression and tension.
Spongy bone tissue lacks Haversian canals, which are found in compact bone tissue. These canals are responsible for carrying blood vessels and nerves through the bone. Spongy bone also lacks a dense arrangement of bone cells, giving it a more porous and lightweight structure.
makes bones lightweight by it's holes and able your bones to move much easier because it makes bones lightweight by it's holes so it's job is to make your bones lightweight and to make your bones move easier
Because most of the bone is made of spongy bone and it looks like a sponge in the inside so it is less dense and that is why it is light.
because most bone is made of spongy bone it looks like a sponge inside so it is less dense making it lighter.
