Protection:  Bones are hard and strong so that they can protect  important organs. 

• Examples: Your skull  protects your brain and your ribcage protects your heart.

• Red blood cells transport oxygen, nutrients and hormones.

• White Blood cell: Fights off infections and harmful pathogens  in the body. 

Respiratory System: System that is responsible for bringing in oxygen and removing carbon dioxide.

• Alveoli: Balloon-shaped structures in the lungs that are responsible for gas exchange.

Muscular System: System that is most responsible for movement.

Skeletal System: System that is a rigid framework for the body and protects major organs. It also produces the red blood cells.
