Bones are the rigid, connective tissue framework of the human body, providing support, protection, and enabling movement. They are made up of two main types of bone tissue: compact bone, which is dense and hard, and cancellous bone, which is sponge-like and found inside the compact bone. Bones also contain bone marrow, where blood cells are produced, and are constantly being remodeled and strengthened throughout life.

**Bone** is the human skeleton’s chief purpose that supports that body’s structure as the most fertile segment. It encourages, confirms and sustains the extremity’s contour, additionally also provides bases for muscular embolism. The skeletal elements consist of collagen fibers inorganic components being a source of strength, predominantly calcium phosphate. Bone although very rigid is not an isolated entity as it keeps changing due to the work of the bone forming cells, osteoblasts and bone resorbing cells, osteoclasts. Bone acts as a storehouse of minerals especially Calcium and Phosporus, while also acting as the male organ of blood. In addition, bones help to house the brain, lungs and heart and provide sustenance for the excess studies forces and functions of the body in terms of health and organization.

Bone as an essential and living tissue serves as the framework of the human body by giving the body form, support, and protection. Bone is made of living cells embedded in the mineral matrix, mainly of calcium phosphate, which imparts strength and rigidity to the bone. Cellular constituents of bone include osteoblasts, which make bone cells; osteocytes, which maintain the bone; and osteoclasts, eating up the bone in the course of remodeling. Bones are not static and continually change themselves by adapting to stress and repairing injuries. Aside from giving the body-provided structure, bone works as a reservoir of minerals such as calcium and phosphorus, both of which can be released into the bloodstream upon demand. Also, bones contain bone marrow, producing blood cells.

Bones are rigid organs that form part of the endoskeleton of vertebrates. They provide structure, support, and protection to the body, as well as facilitate movement. Bones are composed mainly of collagen fibers and mineralized tissue, primarily calcium phosphate, which gives them strength and hardness. They serve as a reservoir for minerals like calcium and phosphorus, which can be released into the bloodstream when needed. Additionally, bones house bone marrow, where blood cells are produced. Bones are constantly being remodeled through the processes of bone resorption and bone formation.
