FORMATION OF BONE:
Bone is a complete stiff organ, which is part of the endoskeleton of vertebrates. They are very helpful to move, protect, and support the body's organs are different. They also produce red and white blood cells and store minerals. This bone tissue is a type of dense connective tissue such as bones come in various shapes and structures of complex internal and external. They are lightweight but strong and hard to fulfill their function much some.

Connective tissue is also called osseous bone tissue that is very helpful for the rigidity and honeycomb-like three-dimensional internal structure. osseous tissues composed of bone cells called osteocytes are surrounded by substance, filled with hard between calcium salt.

During fetal development, fetal bones consist of cartilage tissue, which resembles a network of reinforcement, and more flexible and less lack of calcium salts in the solid, soft cartilage occurred and spread throughout the lives of individuals after birth. General replacement intercellular substance of cartilage and bone cells with immature and calcium deposits called ossification or bone formation.

Osteoblasts is not yet mature osteocytes that produce bone tissue exchange cartilage during hardening. Where osteoclast-class attempts to break is a big cell that functions to reabsorb, or digest the bone tissue. The osteoclasts also called phagocytes that digest bone bone tissue to die from the side of the bone and thereby enlarge the cavity in the bone so that bone does not become more thick and heavy. Each time you break the bone, osteoblasts lay bone mineral material which is also called the salt of calcium, bone and osteoclasts remove excess dirt.

On the right supply of calcium and phosphorus into bone tissue, bone formation is dependent to a large extent. These minerals must be taken to the body with sufficient amounts of vitamin D. Part calcium through the small intestine lining and into the bloodstream, Vitamin D is very helpful.

osteoblastic activity once the enzyme calcium and phosphorus in bone that causes the formation of calcium phosphate which is the substance of providing quality characteristics of hard bone.
