A bone is a rigid organ that constitutes part of the skeleton in most vertebrate animals. [1] Bones protect the organs of the body, produce red and white blood cells, store minerals, help regulate acid-base homeostasis, provide structure and support for the body, and enable mobility and hearing. Bones come in a variety of shapes and sizes and have complex internal and external structures. [2 ...
Bone is a rigid body tissue consisting of cells embedded in an abundant hard intercellular material. Bone tissue makes up the individual bones of the skeletons of vertebrates. Its two principle components are collagen and calcium phosphate.
An introduction to bones. We discuss their function, the different types of bones in the human body, and the cells that are involved.
A typical bone in your body contains 3 types of tissue—a hard outer tissue, a sponge-like inner tissue, and smooth tissue at the ends.

What does bone do? Bone has many important jobs in the body: The skeleton is made of bone to provide a strong framework to support and protect the soft organs (such as the brain, heart, and lungs) from injury. Bone works with muscle to hold up the body when we stand and to move the body when we walk or run. Bone houses the bone marrow, which makes blood cells. Bone stores growth factors and ...
