The Respiratory System: What do we already know? BrainPOP Teaser Page 1 The Respiratory System: What do we already know? BrainPOP Teaser What is digestion? a) Where does digestion begin? How is food broken down further? 3) Food Chain Human Body Systems: Lesson 3
The Respiratory System: Vocabulary Part I Page 2 The Respiratory System: Vocabulary Part I 1) inhale: to breathe air into your body through your mouth or nose. 2) lungs: organs that fill with air when you inhale and empty of air when you exhale. 3) exhale: to breathe out. 4) diaphragm: is the muscle located below your lungs that contracts and expands to control your breathing. Human Body Systems: Lesson 3
The Respiratory System: Vocabulary Part II Page 3 The Respiratory System: Vocabulary Part II 5) bronchi: are the branches of tubes that get smaller and smaller 6) capillary: is a tiny blood vessel. 7) alveoli: are very thin air sacs at the end of the bronchi tubes that aids in the exchange of oxygen and carbon dioxide. 8) diffusion: is the movement of particles from areas of high concentration to low.

The Respiratory System: Main Ideas Page 7 The Respiratory System: Main Ideas What does the respiratory system do? (pg. 134-135) a) It transports the air you breathe and exchanges oxygen and carbon dioxide between your blood and your tissues. Quick Check (pg. 135) -Critical Thinking: Explain how the diaphragm and lungs work together? a) The diaphragm helps the lungs contract and expand which allowing the lungs to take in and push out air.

The Respiratory System: Main Ideas Page 8 The Respiratory System: Main Ideas 2) Where does gas exchange take place? (pg. 136-137) a) The alveoli. Quick Check (pg. 137) -Critical Thinking: Carbon dioxide is a human waste. Is this true for plant, too? a) No. Oxygen is a plant waste. Human Body Systems: Lesson 3
