Work together by moving air in and out of the lungs
Work together to facilitate movement and locomotion
Work together to provide the movement of blood throughout the body
When in contact with the external environment, these systems take in nutrients and oxygen
Act together to bring in and distribute oxygen to the cells
Act together to break down and distribute nutrients to the cells
Together allow you to look around you and see the world
Work together to pick up and filter nitrogen-containing waste from the body
Work together in breakdown and movement of food though the gastrointestinal tract
Metabolic wastes are eliminated by these two systems
Blood brings the brain and neurons oxygen to survive AND then picks up waste (carbon dioxide)
One system produces specialized cells that are used by the other system to distribute oxygen through the body
