Skeletal System

The skeletal system provides bony protection for soft, internal organs.

The thorax (sternum, ribs, and spine) protect the heart, lungs, and other organs.

The framework provides attachment points for muscles, tendons, ligaments, skin and organs.

Bones such as the femur in the legs bear the weight of the upper body.

The spinal column makes the body straight and supports the head.

Larger bones of the skeletal system contain MARROW.

Red marrow is responsible for the production of red blood cells that are responsible for carrying oxygen to body tissues.

White blood cells are also produced that are important for the body immune system.

The skeletal system provides a framework for muscles to attach.

When they contract they PULL on the bones of the skeleton, which act like levers to create movement.

Gliding joints glide over one another an example is your wrist and ankles.

Pivot joints move left and right and up and down for example their head
