  1. Respiratory System Mrs. King 7thGrade Science

  2. HUSTLE • Explain the main function of the circulatory system. • What are the levels of the human body from complex to most basic? • What is an organ? • What is the pH scale? Give examples of items on the pH scale and what their pH is. • How else can we test for an acid/base?

  3. Goal/Preview • TSW recall the parts of each body system and explain their function with 85% accuracy. • Focus: Respiratory • PREVIEW for Today • Respiratory Notes from Support Document • Illustrate respiratory system – discuss impact • PASS Challenge – Impact on breathing?

  4. Respiratory System – Page 11 • Major organs: nose, trachea, bronchi(bronchus), lungs, diaphragm

  5. Respiratory System Notes • Nose – collects air then wets/heats it before it enters the trachea • Trachea – Windpipe, moves air from nose/mouth to the lungs • Bronchi/Bronchus – tubes that take air from the trachea to the lungs, one bronchus goes to each lung, part of the bronchus is in the lung and part is outside the lung

  6. Illustrations

  7. Notes… • Lungs – the main organs of the respiratory system where gases are exchanged between air and blood. • Alveoli – where the gas exchange takes place in the lungs • Diaphragm – Muscle that helps the breathing process

  8. Diagrams

  9. Let’s Discuss • Talk with your partner about the respiratory system. How do you think it works inside of you?

  10. PASS Challenge/Reflection • The trachea, bronchi, and diaphragm are all components of the ___________ system. • A. Respiratory • B. Circulatory • C. Immune • D. Cardiovascular • Complete Graphic Organizer • Reflection: Page 10 under illustration • What do you think asthma or other breathing issues have to do with the respiratory system? How does the respiratory system play a part?
