1. Construct your Interactive Notes
• On the cover, write
– Chapter 15: Respiratory System
– Name, period, seat #
– Draw a color picture
• Staple 6 pages of binder paper to the cover
• Number the pages

2. Notes: Overview of Respiration (pg 2)

3. Notes: Overview of Respiration (pg 2)
• Respiration = Exchange of oxygen and carbon
dioxide between the atmosphere and the body
cells

4. Notes: Overview of Respiration (pg 2)
• Respiration = Exchange of oxygen and carbon
dioxide between the atmosphere and the body
cells
• Ventilation = Breathing process

5. Notes: Overview of Respiration (pg 2)
• Respiration = Exchange of oxygen and carbon
dioxide between the atmosphere and the body
cells
• Ventilation = Breathing process
• External respiration = exchange of gases between
the lungs and the blood

6. Notes: Overview of Respiration (pg 2)
• Respiration = Exchange of oxygen and carbon
dioxide between the atmosphere and the body
cells
• Ventilation = Breathing process
• External respiration = exchange of gases between
the lungs and the blood
• Internal respiration = exchange of gases between
the blood and the tissue cells

7. Notes: Overview of Respiration (pg 2)
• Respiration = Exchange of oxygen and carbon
dioxide between the atmosphere and the body cells
• Ventilation = Breathing process
• External respiration = exchange of gases between
the lungs and the blood
• Internal respiration = exchange of gases between the
blood and the tissue cells
• Cellular respiration = Cells use oxygen to make ATP
Glucose + O2 CO2 + H20 + ATP

8. Draw picture (pg 3)

9. Respiratory Organs (pg 2)
• Upper Respiratory Tract
– Nasal cavity: filters, warms, and moistens air

10. • Upper Respiratory Tract
– Nasal cavity: filters, warms, and moistens air
– Pharynx: Throat. 13 cm long (from base of skull to
6th cervical vertebrae). Passageway for air and food

11. • Upper Respiratory Tract
– Nasal cavity: filters, warms, and moistens air
– Pharynx: Throat. 13 cm long (from base of skull to
6th cervical vertebrae). Passageway for air and food
– Larynx: Voice box. Passageway for air between the
pharynx and the trachea. Contains vocal cords.

12. • Lower Respiratory Tract
– Trachea: Windpipe.

13. • Lower Respiratory Tract
– Trachea: Windpipe.
– Primary bronchi: Bifurcation of trachea

14. • Lower Respiratory Tract
– Trachea: Windpipe.
– Primary bronchi: Bifurcation of trachea
– Lungs: Contain bronchial tree. Right lung has 3
lobes, left has 2 lobes

15. With your neighbor
• Make up “stupid mind tricks” to remember
the difference between
– Pharynx (throat) and Larynx (voice box)
– Trachea (for air) and Esophagus (for food)

16. Output (page 3)
• Paste in the diagram on the lower half of pg 1
• Label the parts
• Use the piece of yarn to model the bronchial
tree.

17. Output (page 3): Use only the top half
of the page
• Sketch a human body from the waist up. Draw
in the lungs and a (enlarged) body cell. Then
label the locations of external
respiration, internal respiration, and cellular
respiration. Show the direction oxygen and
carbon dioxide are moving in each process.
