The Skeletal System: The Internal Framework of the Body

The skeletal system is the internal framework (structure) of the body. It is made up of 206 bones and tissue.


Bones hold our body and give us shape. For example, the spinal cord provides support.


The skeleton protects our vital organs. For instance, the skull protects the brain, and the ribs protect our heart and lungs.


Bones allow us to move as a whole body or as individual parts.

Blood Production

Certain bones in the skeleton contain red bone marrow, which produces red blood cells, white blood cells, and platelets.


Our bones can store different minerals, such as calcium.

Endocrine Regulation

Endocrine glands produce hormones, and the skeletal system helps regulate these hormones.
