3. Respiratory System
Brings oxygen into the body

4. Digestive System
Digests food – breaks it down into smaller nutrient molecules
Absorbs nutrient molecules into the bloodstream

5. Circulatory Systems
Transports substances, such as glucose, oxygen, and carbon dioxide throughout the body

6. All Body Cells Mitochondria – site of cellular respiration
Occurs in all body cells
ATP = stored energy
Some cells need more energy than others.
Which ones?

7. Excretory System Removes wastes: Lungs* – carbon dioxide and water
Kidneys – urea and water
Skin – perspiration (water & chemical wastes)
*part of cellular respiration process
