  1. Life Science Unit Overview: Chapter 1 – Structure of Living Things Lesson 1 – Cells Lesson 2 – From Cells to Organisms Lesson 3 – Diversity of Organisms Chapter 2 – Plant Structures and Functions Lesson 1 – Vascular Plants Lesson 2 – Plant Transport Systems Lesson 3 – Photosynthesis and Respiration Chapter 3 – Human Body Systems Lesson 1 – The Human Body Lesson 2 – The Digestive System Lesson 3 The Respiratory System Lesson 4 – The Circulatory System Lesson 5 – The Excretory System

  2. The Respiratory System Lesson Overview: 1) What do we already know? (The Human Body) 2) Vocabulary 3) Drawings 4) Main Ideas 5) Review Human Body Systems: Lesson 3

  3. Page 1 The Respiratory System: What do we already know?BrainPOP Teaser What is digestion? a) Where does digestion begin? a) How is food broken down further? a) Human Body Systems: Lesson 3

  4. 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

  5. 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. Human Body Systems: Lesson 3

  9. 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. Human Body Systems: Lesson 3

  10. 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
