A network of collagenous fibers in the matrix gives bone tissue its strength and flexibility. It is more rigid than other tissues because it contains inorganic salts mainly calcium phosphate and calcium carbonate.

Detoxification: Bone tissue removes heavy metal, and other foreign elements from the blood to reduce their toxic effects in nervous system and other tissues.īone tissue is composed of cells embedded in a matrix of ground substances and fibers.

Acid - Base Balance: Bone Buffers the blood against excessive ph changes by absorbing alkaline mineral salts.

It stores calcium and phosphate and release them according to body's physiological need.

Storage: Skeleton is the body's main mineral reservoir.

Red bone marrow is the major producer of blood cells. It occurs in the bone marrow of certain bones.

Blood Cell Formation: This process is called hemopoiesis.

Movement: Skeletal muscle attached to and the bone to lever to move the body its part.

Protection: It encloses and protection some internal organs such as brain, spinal cord, heart and lungs, reproductive agents.

All the bone provides support for muscle.

Support: It forms the internal framework and support bones of the leg, pelvis and vertebral column and supports the body.

The skeletal system is composed of three types of tissues - bone tissue, cartilages and fibrous connective tissue, which forms the ligaments that hold bones together at the joints. The study of the bones is called oestology. Latter, with increasing age, separate bones gradually fuse so the number of bone decreases.

The adult skeletal system consists of many bones ( 206 bones) but there are about 270 bones at birth and during childhood. The skeletal system consists of bone and other structure that make up the joints of the skeleton. It is a moist changing, productive tissue that is continually resorbed, reformed and remodeled. Bone is a specialized connective tissue that has the strength of cast iron and lightness of pinewood. The word ' skeleton' comes from the Greek word skeleton meaning 'dried up'.
