Lets Get Oxygenated!
KWL Style OHH Yeah!

• Yet another Grant Routine

2
-LGO Instructions I-

• Step 1
• I will introduce a topic/question that you WANT
  to know about. You will have a few minutes to
  jot down any prior information you already KNOW
  regarding the topic in the K column.

3
-LGO Instructions II-

• Step 2
• After you have had a few moments to jot down
  prior knowledge, I will explain the topic via a
  slide or two. You will work to understand the
  topic. I will signify when you are to jot down
  new knowledge in the LEARNED column. You must
  wait for my cue to do this.

4
-LGO Instructions III-

• Step 3
• Then, lastly, you will HIGHLIGHT prior
  information from your K column that still holds
  true after you have learned/grasped the topic.
  Again, you must wait for my cue to do this.
  Follow the directions on the slides!

So, what is respiration anyway? If you are not
too sure, please make an educated guess.

• Please fill in the K part of your sheet

When you have finished filling in your K column,

Respiration Is

• The process by which O2 and CO2 are exchanged
  between cells, the blood and air in the lungs.

8
Lets Figure It Out!

• In order for something to be considered in the
  process of respiration, what must be occurring?
• A. O2 and CO2 being exchanged between cells and
  air.
• B. O2 taken into the body through the lungs.
• C. O2 and CO2 being exchanged between cells, air
  in the lungs, and blood.

9
Oh no
What enters/exits here?

• Dont feel bad though, respiration is commonly
  misunderstood!
• It is not the process of breathing, instead it
  refers to an exchange of 2 gases in 3 different
  spots.

Where are the gases going and coming from?
10
Yes! Take a deep breath, thenWrite down what
you LEARNED!

What structures make up the Respiratory
System?Hint 7 total

• Please fill in the K part of your sheet

13
And the structures are

• Nose
• Pharynx
• Larynx
• Trachea
• Bronchi
• Alveoli
• Diaphragm

Click on the structures to see where they are
located.

structures, click here.

My nose allows oxygen to enter my body, and
allows carbon dioxide to exit my body. Thanks

What are the functions of the Respiratory System
structures?

• Please fill in the K part of your sheet

24
Pharynx
Purple, path of air

• Passageway for food air

White, path food
Path for food air
25
Larynx

• 2 highly elastic folds known as the vocal cords

26
Trachea

• AKA Windpipe a piece of cartilage called the
  epiglottis covers the entrance to the trachea
  when you swallow

27

• Lets see if you have
• these first few
• structures
• What am I pointing
• to?
• The Pharynx?
• The Trachea?
• The Larynx?

28
Not quite! Hint Time!

• I keep these structures clear by thinking...
• PLT (like BLT)
• -Pharynx, Larynx, Trachea
• -the order the structures fall in
• Pharynx FOOD (say it, youll see the fffff
  sound.
• -The pharynx carries the food and air.

29
Oh Yes!

• This tube is the pharynx, it carries both food
  and air!
• You are on your way to becoming a Respiratory
  Expert!

Bronchus

• Each bronchus leads to the lungsto bronchito
  bronchioles

31
Alveoli
Alveoli

• Tiny air sacs surrounded by capillaries

Describe gas exchange in a lung. How do you think
it occurs?

• Please fill in the K part of your sheet

35
You have about 350 million alveoli in your lungs,
giving you lots of surface area. Alveoli look
like little grapes.When you inhale air, oxygen
travels through the nose, pharynx, larynx,
trachea, bronchi and finally into the alveoli
where it dissolves in the moisture on the inner
surface of the alveoliThe oxygen diffuses in
the bloodstream because the concentration of
oxygen is higher in the air in the alveoli than
in the blood. Remember, diffusion is the movement
of molecules from high concentration to low
concentration until both sides are equal.The
carbon dioxide in the blood is in a higher
concentration than in the air in the alveoli, so
CO2 moves out of the blood, and it travels back
through the respiratory system and out into the
air.Did you get all that? Reread if necessary,
this is key!

36
What are you doing to me Mrs. Grant?

• How does that O2 that I inhaled get all the way
  into my blood, and finally my cells?
• Nose, larynx, pharynx, bronchi, alveoli, blood,
  cells.
• Nose, pharynx, larynx, trachea, bronchi, alveoli,
  blood, cells.
• Nose, pharynx, trachea, bronchi, alveoli, blood,
  cells.

37
Oh yeah!

• I am impressed. You have the order of how the
  oxygen gets to the alveoli, but how does it get
  into the bloodstream, and then to the cells?
• Diffusion
• Symbiosis
• Catalysis

38
Come now, you have not even heard this term
before in Biology.Hint It is a concept we have
continually talked about all year.
39
Uh oh

• Remember Bacon, Lettuce Tomato?
• Woops, I mean, Pacon, Lettuce Tomato?

40
Yes! Diffusion of O2 CO2

Diaphragm Dilemma!

• Take a deep breath in, and hold it
• Currently, is your diaphragm
• contracted or relaxed?
• If you arent correct, I will re-explain.

How is breathing controlled?

• Please fill in the K part of your sheet

51
Medulla Oblongata

• Medulla oblongota monitors the CO2 level in the
  blood

52
When the Medulla Oblongata senses high levels of
CO2 in the blood then what? Knowing what you
know about the Respiratory System, make an
educated guess.

• It signals the nose to suck in air.
• It signals the diaphragm to relax.
• It signals the diaphragm to contract.

A clean, healthy lung Observe this lung
58
Iccky! A dirty, unhealthy lung. How do you
think this relates to the bronchi?
There is no relation.
The air has a difficult time moving through the
bronchi.
59
There is most definitely a correlation!

• Any infringement in the bronchiole tubes will
  cause a difficulty in breathing.
• Remember, smoking stinks!

Choose the description that best summarizes what
is happening in this image.

• Mrs. Grant is respiring to bring oxygen to her
  lungs.
• Mrs. Grant is respiring, which means she is
  breathing.
• Mrs. Grant is respiring bringing oxygen to all of
  her cells,
• and eliminating carbon dioxide, the waste product
  of her cells.

Do you feel Oxygenated?
Ohh yeah!
