What is the main function of the skeletal system?

Great Answer

Professionally Researched. (What's this?)

The body's skeletal system consists of 206 bones, which provide the overall shape of the human body. In addition to providing this shape, the skeletal system has a variety of other important functions.

Structural Support

The main function of the body's skeletal system is to provide structural support for the body. The bones in the body's skeletal system are the framework to which the body tissues and organs are attached.

Protection

In addition to providing support for the body's organs, the skeletal system also provides protection for these important organs. For example, the rib cage protects the lungs and heart, while the skull protects the brain.

Movement

Although muscles are ultimately responsible for body movements, they would be unable to produce movement if they could not push off against the bones. Essentially, the skeletal system serves as an anchor for body movement.

Blood Cell Production

Red blood cells are produced by the bone marrow inside some of the body's bones. Without the skeletal system, the body would be unable to replenish its blood supply.

Storage

A variety of minerals, such as calcium and phosphorus, are stored inside the bones. When the body's level of these minerals becomes low, they are pulled out of the skeletal system storage area.
