Lesson 12
Outcome 12: List the different
parts of blood and what they do.
Task
• Use the internet to research and complete
the questions from activity 2.
Journal and Push Yourself
• Outcome 12: List the purpose of each
constituent that makes up blood
Lesson 13
Outcome 13: Explain the
importance of knowing blood
types

Lesson 14
Outcome 14: Compare the
differences between the 3 blood
vessels
Where does blood go?
• Blood needs to go to
all living cells
including muscles,
organs and even
bones.
• This is so living cells
get essential oxygen
and nutrients
Blood
Movement
• Blood flows around
the body via the
pumping action of the
heart.
• It travels through
“pipes” called blood
vessels
Blue blood?
• You can see
evidence of blood
vessels by looking
at your wrist.
• Why does the
blood appear
blue?
Valves in the Vessels
• Valves in the blood
vessels help the
vessels to behave like
a one way street.
• Blood travels in the
same direction around
the body
Task
• Work through activity 4 to gather more
information about the blood vessels
• Draw your own diagram of the circulation
system which shows where the different
blood vessels are located
Journal and Push Yourself
• Outcome 14: Compare the differences
between the 3 blood vessels
Lesson 15
Outcome 15: Label a diagram of the
heart and list the order that blood flows
through the heart and body
Task
• Take a sheep’s heart and identify some of
the parts from the outside:
– Left side
– Right side
– Major vein from the body
– Aorta
– Pulmonary artery and vein
Ready to make a cut
• Find the groove between the left side and
right. Carefully cut either side of this
groove.
Inside the Heart
• Observe:
– How many chambers can you find?
– Where do the chambers lead to? What leads
into the chambers?
– What separates the chambers?
Task
• Collect a diagram of the heart from the teacher and
complete the labels
• Watch video “Blood circulation in Heart”
• While watching, list the correct order of the blood as it
travels around the body:
– Left ventricle, right atrium, lungs, rest of the body, left atrium,
right ventricle.
• Answer the questions from activity 5
• Complete the questions from activity 6
Journal and Push Yourself
• Outcome 15: Label a diagram of the heart
and list the order that blood flows through
the heart and body
• Many parts of the body have the prefixes
“superior” and “inferior”. Eg: superior vena
cava. What do these terms mean to a
biologist or doctor?
Heart Rate Investigation
• Prepare an investigation which helps to
answer the following aim:
• “How is heart rate related to exercise?”
• You will need a more specific hypothesis
to help answer this problem.
Lesson 16
Outcome 16: Describe the causes and
treatments for heart diseases
Video
• Watch the following video on “Heart
transplant surgery”.
• What were some of the issues that needed
to be considered during the procedure?
Task
• Read through Activity 9, silently
• Answer questions 1-6
Discussion
• Upon your death, a sick person may be
able to make use of your healthy organs to
increase their own life expectancy through
an organ transplant.
• Who should decide if your organs are
transplanted after your death?
Who should decide?
• Make a list of the stakeholders who might
be involved in the decision
• Of these stakeholders, what are their
reasons for being involved in the decision?
• Who is the most important stakeholder?
Who is the least important?
Facts
• 1. You must register to be an organ donor
if you are over 18 years old
• 2. After death, despite being registered,
your family has the right to say “no”.
• 3. If your family cannot be contacted, any
other person you may know may be asked
for final consent.
Tell someone
If you register to be a donor…
Tell your family!
Journal and Push Yourself
• Outcome 16: Describe the causes and
treatments for heart diseases
• How many Australian people suffer from
heart related diseases?
Summary Lesson
Collect assignment
&
Video summary
A summary so far
• Watch the video “Body Systems” available
on clickview.
• While watching, complete the worksheet
and be prepared to give your answers at
the end.
Lesson 17
Outcome 17: List the 3 organs that
excrete wastes from the body. List
what waste is excreted by each organ
Notes
• The excretory system is responsible for
the removal of metabolic wastes.
• Metabolic wastes are the unnecessary
products produced by chemical
processes in the body.
• It’s like the body’s form of throwing away
the rubbish.
Not just the kidneys!
• Skin
Lungs
What is the waste product excreted by the skin and lungs?
What’s not excretion?
• Faeces is not a waste
product of the excretion
system.
• Why?
Task
• Activity 10 – questions 1 to 4
• Activity 11 – complete the procedure
Journal and Push Yourself
• Outcome 17: List the 3 organs that excrete
wastes from the body. List what waste is
excreted by each organ
Lesson 18
Outcome 18: Describe the
structure and purpose of joints in
the skeletal system
How many?
• Write down on a scrap piece of paper how
many bones you think are in the human
body.
• If you already know this answer. Have a
guess at how many bones are in your left
foot.
Task
• Visit http://bit.ly/tfDU
• Use this resource to help you name the bones in
the human body.
• OR
• Collect a cut out worksheet to put together a
simplified skeleton and name the parts.
Task
• 1 minute paper:
•GET
What
are theTO
purposes
READY
WRITE!!of the skeleton?
Joints
• If the skeleton was only
one piece, you would be
like a statue, unable to
move.
• The bones meet at joints
which allow movement.
Task
• Group Task:
• What purpose
does each
section of the
joint serve?
• Hint: what does
it attach to and
what type of
surface does it
have?
Task
Draw or find a diagram of a typical joint and
make a table which summarises the
purpose of the ligament, cartilage and
synovial fluid.
(look at activity 16 for clues)
