The skeleton is also referred to as the skeletal system. The skeletal system is comprised of 206 bones and is divided into two distinct parts called the axial and appendicular skeleton.
Protection
The skeleton protects the vital organs of the body. The brain is protected by the skull. The heart and lungs are protected by the ribs and sternum.
Movement
Body movement is achieved by the interaction of the skeletal and muscular system. According to the American College of Sports Medicine, bones are the rigid levers for locomotion.
Blood Production
Marrow, found is some bones, is responsible for blood production. The bone marrow produces millions of red blood cells per second.
Mineral Storage
Bones act as a storage unit for minerals such as calcium and phosphorus. If there is an excess of calcium and phosphorus, there is build-up in the bones. If calcium and phosphorus are in low supply in the body, they are withdrawn from the bones.
Skeletal Divisions
The axial skeleton protects the organs of the head, neck and chest. The appendicular skeleton connect the appendages to the axial skeleton.
