  • Supports and give structure to the body.
  • Protects body parts (brain, lungs, heart, spinal cord, liver, kidneys, and endocrine glands). Bones are the organs of the skeletal system. The bones of the skeletal system protect the soft internal organs of our body.
  • Skull forms a protective encasement for the brain. Ribcage, dorsal vertebrae, ribs and the sternum, encloses heart and lungs of vertebrates.
  • Helps move the body along with the muscles. The skeleton works as a place of attachment for the skeletal muscles.
  • Skeletal system stores minerals, calcium phosphate and fat.
  • It produces blood cells within red bone marrow.

The human skeleton is composed of the axial skeleton which lies in the midline of the body (skull, ribs, spine, and sternum) and the appendicular skeleton includes Pectoral girdle, pelvic girdle, and the upper and lower limbs (arms and legs, scapula, clavicle, and pelvis).
