functions of skeletal system?

The skeletal system in the body provides the shape, supports and protects organs and the soft areas of the body. Its others functions are bodily movement, producing blood for the body, and storing minerals that the physical structure needs.

Shape and Support
The skeleton is made up of various bones and provides the framework for the body. Thus the skeleton provides the basic shape and structure for the body. 
The bones are like the structural members of a building, and all of the organs, muscles and skin are incorporated with the bones, just like the furnishings, rooms, walls, and finishing of a building. 

The skeleton protects organs in the body. Bones can cover and protect many of the major organs. 

  • cranium: protects the brain
  • ribs/sternum: protects the lungs, heart and digestive organs
  • pelvis: protects and supports the digestive and reproductive organs
  • spinal column: protects the major nervous branching into the entire system
  • mandible, maxilla and teeth protect the tongue and buccal cavity.

Blood Cell Production
Inside of the long bones there is a cavity that is filled with a substance called Bone Marrow that produces blood cells and repairs damaged blood cells. 

The bones of the skeleton are the levers that help the body move in different directions and in different ways. Bones anchor muscle to provide movement.The bones by themselves can't move without the muscles that are connected to them. 

Mineral Storage
Mineral is a substance that the body needs to carry out all of the bodily functions like thinking, breathing and moving around. One of the minerals that the body needs is calcium. Calcium is a major part of bone, and this is where the body stores its calcium. The less calcium the bone has, the weaker it will become. In case the body does not get enough calcium from the daily intake of food, it will take the calcium it needs from the bones.
