  1. DO NOW

  2. Teacher Demo: Breathing & Bromothymol Blue BROMOTHYMOL BLUE: What are you breathing out? When the teacher exhales into the Bromothymol Blue, then ______________________________ (what will happen?) READ THE PARAGRAPH on Bromothymol blue. 1) What happened when the teacher breathed out into the bromothymol blue? 2) Why do we inhale? 3) Why do we exhale? What proof do you have?

  3. Respiratory System BrainPop: Respiratory System

  4. Respiratory System (Lung Model Handout) The function of the respiratory system is to provide oxygen to your body cells and remove carbon dioxide. O2 CO2

  5. Lung Model Write the name of the system that we are exploring. Describe your observations as you pull down on the balloon. What do you see?

  6. Respiratory System Reading • Tape this reading on to page ____ • Underline the body system • Put boxes around the structures of the system • Label these structures on the picture

  8. The Respiratory System The Incredible Human Machine(6:30-8:30)

  9. The Pathway of Air Foldable

  10. 1. Nasal Cavity(or oral cavity) • Air enters the body through the nostrils (your nose) most of the time • It is lined with a ciliated mucus membrane which filters, warms, and moistens the air

  11. 3. Trachea • The main airway in the human respiratory system. • It contains rings of a tough tissue (cartilage) which keep the trachea open.

  12. 4. Bronchi Bronchi is plural. Both bronchi Bronchus is singular. One bronchus. • Two tubes that branch off the trachea. • The bronchi are ringed with cartilage. • Each bronchus extends to the lungs where the tubes become smaller.

  13. 5. Bronchioles • Smaller and smaller passageways that extend from each bronchus. • The bronchioles are found in the lungs and not ringed with cartilage.

  14. 6. Alveoli • Oxygen leaves the alveoli, enters the red blood cells and is returned to the heart to be pumped to all your body cells. • Carbon dioxide is exhaled when you breathe out. • The lungs are made of about 300 million of these tiny air sacs. • When you breathe in air fills the alveoli.

  15. Gas Exchange in the Alveoli

  16. ELABORATE: USE YOUR FOLDABLE TO FILL IN THE LABELS OF YOUR LUNG MODEL SHEET:

  17. EXIT TICKET • What are the major structures of the respiratory system? • What is the function of the respiratory system?
