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

13
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

Task

• Take a sheeps heart and identify some of the
  parts from the outside
• Left side
• Right side
• Major vein from the body
• Aorta
• Pulmonary artery and vein

18
Ready to make a cut

• Find the groove between the left side and right.
  Carefully cut either side of this groove.

19
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?

20
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

21
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?

22
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.

23
Lesson 16

• Outcome 16 Describe the causes and treatments
  for heart diseases

24
Video

• Watch the following video on Heart transplant
  surgery.
• What were some of the issues that needed to be
  considered during the procedure?

25
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?

27
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?

28
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.

29
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?

31
Summary Lesson

• Collect assignment
• Video summary

32
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.

33
Lesson 17

• Outcome 17 List the 3 organs that excrete wastes
  from the body. List what waste is excreted by
  each organ

34
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.
• Its like the bodys form of throwing away the
  rubbish.

  joints in the skeletal system

41
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.

43
Task

• 1 minute paper
• What are the purposes of the skeleton?

GET READY TO WRITE!!
44
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.

45
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?
