The Skeletal System

Here is a diagram of the skeletal system and many of  the major bones in it

What Does it Do?

The skeleton protects and supports the body. It works alongside the muscular system to help you move. Your skull and ribs play an important role I'm protection because you skull protects your brain and your ribs protect you heart, lungs and other internal organs from impact.

Why is it important?

The skeleton important because it provides support, protection, and movement. Without the skeleton, the human body would just be a blob of water filled tissues

Parts of the Skeletal System

Some of the major bones are the skull, maxilla and mandible (head), clavicle, sternum and ribs(chest), humerus and radius (arm), and the femur, tibia, and fibula(leg).

In total the skeleton has 270 bones at birth, but some bones, especially in the skull, eventually fuse together creating the 206 bones you have once you're an adult.

How It Maintains Homeostasis

The skeletal system maintains homeostasis by producing new red blood cells as the old ones die off. It also helps maintain the level of calcium in the blood stream.
