• TRUE OR FALSE
• 1. Respiration is when structures and organs move
  oxygen into the body and waste gases out of the
  body.
• 2. Breathing can help respiration when its waste
  gases move out of the body.
• 3. Respiration is the chemical reaction that
  happens when oxygen delivered to the cells is
  used to release energy from glucose.

51

• 4. So when you breathe out you are using cell
  respiration.
• 5. Respiration spreads necessary items into cells
  that need it.
• 6. Breathing is the movement of the chest that
  brings air into the lungs and removes gas.
• 7. Respiration is the process when CO2 and H2O
  molecules are carried back to the lungs in the
  blood.

52

• 8. Respiration is when oxygen is being
  transported to your cells.
• 9. Cellular respiration is the part of breathing
  that removes CO2 and H2O molecules.
• 10. We inhale air containing waste products.
• 11. Breathing is a voluntary process while
