Learning Targets (What must I be able to do to reach mastery?)
1. I can define: tissue, organ, organ system and organism.
2. I can describe the four types of tissue.
3. I can describe the function of the organs in these organ systems:
*circulatory
*digestive
*respiratory
4. I can explain how organ systems depend on each other (such as the digestive and
respiratory)
5. I can describe the levels of organization of an organism.

Pages 62-63 Modeling Lungs
1. What system of the body does this model represent?_______________________
What parts of the body make up this system?___________________________________
_____________________________________________________________________
2. Explain which parts of the model represent the lungs, chest cavity, and diaphragm.

1. In your lungs are thousands of air sacs called alveoli. Because of these alveoli, the
surface area of your lungs is huge. Look at the lung tissue on screen. Now look at the
model lung.
2. The red paper represents the outer part of the lung. The yellow tubes represent the
alveoli. Compare the area of the yellow sheets to the area of the red sheet.
How did adding the yellow tubes affect the inside surface area of the red cylinder?
