The Skeletal System[edit]

The human skeleton.

The Skeletal System is made of all of the bones in the body. It protects the reproductive organs and is a place for muscles to attach. Bones are a very important part of the human body. Without them, we would simply collapse, and be very unstable. They support all of our tissue and muscles, and they are very difficult to break.

The inside of the bones is called the bone marrow. This is where most blood cells are made.
