Homework: NONE - Enjoy the weekend Do Now: Based on last nights
reading, what is the function of the respiratory system? How is
this different than what you wrote down for yesterdays Do Now? How
does this relate to cell respiration? Todays Objectives: Describe
the difference between structure and function, and explain how an
objects structure relates to its function Describe the structures
and functions of respiratory system organs, and explain how they
relate to each other Bio 9B: Thursday, 12.9.10 Title: Respiratory

Purpose of the Respiratory System Objectives for Class:
Describe the difference between structure and function, and explain
how an objects structure relates to its function Describe the major
structures and functions of all organs in the respiratory system
Transport O 2 from the air into the bloodstream Dispose of CO 2
from the bloodstream into the air Link to CELL RESPIRATION: Oxygen
is needed by cells for cell respiration to produce ATP Carbon
Dioxide produced from cell respiration is exhaled through

Structures of the Respiratory System Objectives for Class:
Describe the difference between structure and function, and explain
how an objects structure relates to its function Describe the major
structures and functions of all organs in the respiratory
system
Slide 26
Structures of the Respiratory System: Mouth & Nose : Air
enters the body; gets moistened/filtered Trachea (aka windpipe):
The main airway to the lungs. Objectives for Class: Describe the
difference between structure and function, and explain how an
objects structure relates to its function Describe the major
structures and functions of all organs in the respiratory
system
Slide 27
Lungs: Main organs of the respiratory system where gas exchange
takes place. Bronchi: Tubes that branch off from trachea. One major
bronchi for each lung that branches into smaller and smaller
branches in the lung Note: The smaller branches of the bronchi are
called bronchioles, but we will just call all of the branches
BRONCHI. Structures of the Respiratory System: Major Bronchi
Branching Objectives for Class: Describe the difference between
structure and function, and explain how an objects structure
relates to its function Describe the major structures and functions
of all organs in the respiratory system Smaller Bronchi Branching
in the lung
Slide 28
Alveoli: Tiny air sacs at the ends of the bronchioles where gas
exchange takes place. Look like GRAPES! Surrounded by a network of
capillaries tiny blood vessels that trade O 2 and CO 2 with alveoli

Slide 32
Complications of the Respiratory System 6 Groups: Smoking (use
pg. 961-963 in book) Pneumonia Cystic Fibrosis Bronchitis Asbestos
Asthma
Slide 33
Complications of the Respiratory System Task I - In Small
Groups of 3 and 4: Research one complication of the respiratory
system and be able to describe it to the other students in your
group. In the Diagram Box, draw how your issue damages the
respiratory system by modifying and annotating the diagram of the
lung. In the Information Box, describe the characteristics of your
issue, explain how it affects the structures of the respiratory
system, and describe how it effects the function of the respiratory
system (you can think of these as symptoms). Task II - Jigsaw into
groups with members from different groups: Each person shares the
information from their issue As each person presents, all other
group members should be comparing and contrasting that issue to
their own. Task III - Individually: Compare and contrast 2 of the
respiratory system complications to determine their similarities
and differences

Complications of the Respiratory System Task I - In Small
Groups of 3 and 4: (15 min) Research one complication of the
respiratory system and be able to describe it to the other students
in your group. In the Diagram Box, draw how your issue damages the
respiratory system by modifying and annotating the diagram of the
lung. In the Information Box, describe the characteristics of your
issue, explain how it affects the structures of the respiratory
system, and describe how it effects the function of the respiratory
system (you can think of these as symptoms).

Homework: Use the study guide on the back of this sheet to
study for tomorrows QUIZ. Collect Late Work Pass Back Lab Reports
Do Now: Take the balloon and, without stretching it, try to inflate
it. Observe what your body is doing to inflate the balloon. Mark
your observations in your notebook Todays Objectives: Describe the
difference between structure and function, and explain how an
objects structure relates to its function Describe the structures
and functions of respiratory system organs, and explain how they
relate to each other Bio 9B: Monday, 12.13.10 Title: Respiratory
System: Structures & Functions Day 2
Slide 37
Debrief of Balloon Blowing: What did you observe your body
doing to inflate the balloon? Quick Activity Holding your Breath:
Hold your breath for as long as you can (on my start) While you are
holding your breathe, observe what happens to your body the longer
you try not to breathe. Record these observations in your notebook.
Debrief of Holding Breath: What did you observe about your body as
you tried to hold your breath? Structures of the Respiratory
System: Objectives for Class: Describe the difference between
structure and function, and explain how an objects structure
relates to its function Describe the major structures and functions
of all organs in the respiratory system
Slide 38
Two Important Processes in the Respiratory System: (Dont need
to write this down just a preview) Breathing controlled by the
diaphragm Gas exchange happens in the alveoli Objectives for Class:
Describe the difference between structure and function, and explain
how an objects structure relates to its function Describe the major
structures and functions of all organs in the respiratory
system
Slide 39
Diaphragm: Large flat muscle that controls breathing Located at
the bottom of the chest cavity When it contracts, you inhale
Structures of the Respiratory System: Objectives for Class:
Describe the difference between structure and function, and explain
how an objects structure relates to its function Describe the major
structures and functions of all organs in the respiratory
system
Slide 40
The Process of Breathing Inhaling: 1. Diaphragm contracts &
lowers 2. Volume of lungs increases 3. Air rushes in (through
mouth/nose, trachea, bronchi, to alveoli) to fill the space
Exhaling: 1. Diaphragm relaxes & bends upward 2. Volume of
lungs decreases 3. Air is forced out ( from alveoli through
bronchi, trachea, mouth/nose ) Objectives for Class: Describe the
difference between structure and function, and explain how an
objects structure relates to its function Describe the major
structures and functions of all organs in the respiratory
system
Slide 41
Slide 42
Slide 43
The Process of Gas Exchange Oxygen diffuses from alveoli into
capillaries (tiny blood vessels) and binds to red blood cells
Carbon dioxide diffuses from capillaries into alveoli Objectives
for Class: Describe the difference between structure and function,
and explain how an objects structure relates to its function
Describe the major structures and functions of all organs in the
respiratory system Gas exchange the diffusion of oxygen and carbon
dioxide across cell membranes Happens in the alveoli of the
lungs
Slide 44
Slide 45
The Process of Gas Exchange Gas exchange in the lungs needs
HUGE AMOUNTS of surface area for enough O2 and CO2 to diffuse!
Lungs contain 1.3 million alveoli!! The total surface of all the
alveoli would cover half a tennis court!!
