what does the skeletal system do?

Answer 1

The skeleton has six main functions:


Support
The skeleton provides the framework which supports the body, allowing large animals to maintain their shape.


Attachment
The bones of the skeleton provide an attachment surface for muscles, tendons and ligaments.


Movement
Movement in vertebrates is dependent on the skeletal muscles, which are attached to the skeleton by tendons. Without the skeleton to give leverage, movement would be greatly restricted.


Protection
The skeleton protects many vital organs: The skull protects the brain, the vertebral column protects the spinal cord, and the ribcage protects the lungs and the heart.


Blood cell production
The skeleton is the site of haematopoiesis - the generation of blood cells, that takes place in red bone marrow (which is why bone marrow cancer is very often a terminal disease)


Storage
Bone also serves as a mineral storage deposit in which nutrients can be stored and retrieved. Calcium, especially, can be released by dissolution of bone tissue under the control of 1,25-dihydroxyvitamin D3 during periods of low calcium intake.
