You need:
• Clean paper / Pencil
• Heart diagram (labelled/colored)
• Word wall mini-poster
Warm Up: (on your WARM UP sheet)
What are the parts of the blood?
I CAN: identify the structures and function of the
circulatory system.
I CAN: identify the structures and function of the
respiratory system.
Be the positive.
It takes many “put-ups” to
cancel a “put-down.”

The Digestive System
The digestive system has
3 main functions:
1. It breaks down food
into particles that the
body can use.
2. It absorbs nutrients
into the blood.
3. It eliminates waste
from the body.
Mouth
Esophagus
The Excretory system
Eliminates waste
from the body.
What does it do for us?
Our circulatory system…
• Delivers necessary
materials (like oxygen
and sugar) to the entire
body in the blood,
• Removes waste products
from cells, and
• Helps fight disease by
transporting immune
cells in the blood.
• From Body
So, the detailed path of blood in
your body would look like this:
• Right Atrium
• Right Ventricle
• To Lungs
• From Lung
• Left Atrium
• Left Ventricle
• To Body

What carries the blood?
• BLOOD VESSELS
are the hollow tubes
that carry your
blood around your
body.
• There are 3 TYPES:
– ARTERIES
– CAPILLARIES
– VEINS
What is your blood?
Red Blood
Cells carry
oxygen.
White blood
cells fight
disease.
Platelets form
blood clots to stop
you from bleeding
too much.
Tracking a Hurricane
How can we use maps, satellite, and
radar to predict where this hurricane
will hit?

So what happens if you don’t
take care of your circulatory
system?
Not enough good stuff to your body
Build up of bad stuff in your body
Heart Attack!
- Breathe in and out…
What is the RESPIRATORY SYSTEM?
• The system of the body that
deals with BREATHING.
• It consists of the NOSE,
PHARYNX, TRACHEA,
BRONCHIAL TUBES, and
LUNGS.
- Breathe in and out…
What is the FUNCTION of the
System?
Respiratory
• To DELIVER OXYGEN to the
body.
• To REMOVE CARBON
DIOXIDE from the body.
- Breathe in and out…
Why does the body need oxygen?
• The body’s CELLS use OXYGEN to
release ENERGY to the body.
• CELLULAR RESPIRATION is the
CHEMICAL REACTION that uses
GLUCOSE & OXYGEN to release
ENERGY.
• CARBON DIOXIDE is a WASTE
PRODUCT of this chemical reaction.
- Breathe in and out…
Which systems work together?
• RESPIRATORY SYSTEM gets OXYGEN
from the air.
• DIGESTIVE SYSTEM gets GLUCOSE
from food.
• CIRCULATORY SYSTEM DELIVERS
oxygen and glucose to cells.

In the cells,
respiration uses
glucose and oxygen
to release ENERGY.
What path does AIR flow?
• Try it
• Use the words on your table and work with
your elbow partner to put them in order.
• Raise your hand when you are done.
- Breathe in and out…
What path does AIR follow?
•
•
•
•
NOSE
PHARYNX
TRACHEA
BRONCHIAL
TUBES
• LUNGS
(alveoli)
- Breathe in and out…
What happens in each part?
NOSE – in the nasal cavity,
the air is:
– Warmed,
– FILTERED, and
– moistened.
(Mucus and nasal hairs keep out
dust, pollen and other particles).
• PHARYNX – air passes through the THROAT when
breathing. The EPIGLOTTIS covers the trachea when you
SWALLOW to prevent FOOD from entering the trachea
when you eat/drink.
- Breathe in and out…
What happens in each part?
• TRACHEA – is the WINDPIPE that
leads to the lungs. It is a TUBE with
RINGS OF CARTILAGE.
• BRONCHIAL TUBES – are the
the short tubes that branch off the
trachea TO CARRY AIR TO
the LUNGS.
- Breathe in and out…
What happens in each part?
• LUNGS – inside the lungs, the bronchi branch into
SMALLER TUBES. At the end of the smallest tubes,
are structures called ALVEOLI.
• ALVEOLI – are AIR SACS,
surrounded by CAPILLARIES.
This where BLOOD picks up
OXYGEN and gets rid of CARBON
DIOXIDE.
- Breathe in and out…
What happens in the ALVEOLI?
• GAS EXCHANGE - Blood from the
body enters the lungs. In the alveoli,
the blood GETS RID OF CARBON
DIOXIDE and PICKS UP OXYGEN
before returning to the heart to take
oxygen
to rest of the body.
How do we BREATHE?
How are BREATHING &
SPEAKING related?
• Air that you BREATHE OUT when you exhale
also helps you SPEAK.
• Your LARYNX is your VOICE BOX which has 2
VOCAL CHORDS that move and
produce sound when air passes
through the opening between
them.
Larynx

• Helium to speak
Let’s make a demo!
• At your table, you have a bottle, balloons, rubber
bands, and straw “thing”
• Stretch the balloon over the bottom of the
bottle…the open area. Secure the balloon with a
rubber band.
• Place the straw “thing” into the bottle and screw
the top on.
• Pinching the balloon that you stretched on the
bottle, pull down. What happens to the balloon
on the straw “thing”? Why?
Are there any
questions?
