1Body Works Circulation, Excretion and the Skeleton D. Patterson
2Outcome 12: List the different parts of blood and what they do. Lesson 12Outcome 12: List the different parts of blood and what they do.Relevant Test Qs:Name the liquid that makes up most of the volume of blood.Name the blood cell that carries oxygen and carbon dioxideThe name of the pigment that makes red blood cells appear red is called:
3TaskUse the internet to research and complete the questions from activity 2.
4Journal and Push Yourself Outcome 12: List the purpose of each constituent that makes up blood
5Outcome 13: Explain the importance of knowing blood types Lesson 13Outcome 13: Explain the importance of knowing blood types
7Outcome 14: Compare the differences between the 3 blood vessels Lesson 14Outcome 14: Compare the differences between the 3 blood vessels
8Where 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
9Blood MovementBlood flows around the body via the pumping action of the heart.It travels through “pipes” called blood vessels
10Blue blood?You can see evidence of blood vessels by looking at your wrist.Why does the blood appear blue?
11Label arteries, veins, capillaries Label arteries, veins, capillaries. Label arteries as leading away from heart, high pressure but low volume. Veins as low pressure but high volume, toward the heart. Colours indicate oxygen levels.
12Valves in the VesselsValves in the blood vessels help the vessels to behave like a one way street.Blood travels in the same direction around the body
13TaskWork through activity 4 to gather more information about the blood vesselsDraw your own diagram of the circulation system which shows where the different blood vessels are located
14Journal and Push Yourself Outcome 14: Compare the differences between the 3 blood vessels
15Lesson 15Outcome 15: Label a diagram of the heart and list the order that blood flows through the heart and body
17TaskTake a sheep’s heart and identify some of the parts from the outside:Left sideRight sideMajor vein from the bodyAortaPulmonary artery and vein
18Ready to make a cutFind the groove between the left side and right. Carefully cut either side of this groove.
19Inside the Heart Observe: How many chambers can you find? Where do the chambers lead to? What leads into the chambers?What separates the chambers?
20TaskCollect a diagram of the heart from the teacher and complete the labelsWatch 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 5Complete the questions from activity 6
21Journal and Push Yourself Outcome 15: Label a diagram of the heart and list the order that blood flows through the heart and bodyMany parts of the body have the prefixes “superior” and “inferior”. Eg: superior vena cava. What do these terms mean to a biologist or doctor?
22Heart 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.
23Outcome 16: Describe the causes and treatments for heart diseases Lesson 16Outcome 16: Describe the causes and treatments for heart diseases
24Video Watch the following video on “Heart transplant surgery”. What were some of the issues that needed to be considered during the procedure?
25TaskRead through Activity 9, silentlyAnswer questions 1-6
26DiscussionUpon 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?
27Who should decide?Make a list of the stakeholders who might be involved in the decisionOf these stakeholders, what are their reasons for being involved in the decision?Who is the most important stakeholder? Who is the least important?
28Facts1. You must register to be an organ donor if you are over 18 years old2. 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.
29Tell someoneIf you register to be a donor…Tell your family!
30Journal and Push Yourself Outcome 16: Describe the causes and treatments for heart diseasesHow many Australian people suffer from heart related diseases?
31Collect assignment & Video summary Summary LessonCollect assignment&Video summary
32A summary so farWatch the video “Body Systems” available on clickview.While watching, complete the worksheet and be prepared to give your answers at the end.
33Lesson 17Outcome 17: List the 3 organs that excrete wastes from the body. List what waste is excreted by each organ
34NotesThe 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.
35Not just the kidneys! Skin Lungs What is the waste product excreted by the skin and lungs?
36What’s not excretion?Faeces is not a waste product of the excretion system.Why?Faeces was never absorbed by the body and therefore not used in any chemical processes. It is a digestive waste only.
37Task Activity 10 – questions 1 to 4 Activity 11 – complete the procedure
39Journal and Push Yourself Outcome 17: List the 3 organs that excrete wastes from the body. List what waste is excreted by each organ
40Lesson 18Outcome 18: Describe the structure and purpose of joints in the skeletal system
41How 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.206 in the body26 in a foot
42Task Visit http://bit.ly/tfDU Use this resource to help you name the bones in the human body.ORCollect a cut out worksheet to put together a simplified skeleton and name the parts.
43Task 1 minute paper: What are the purposes of the skeleton? GET READY TO WRITE!!
44JointsIf the skeleton was only one piece, you would be like a statue, unable to move.The bones meet at joints which allow movement.
45Task 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?
46TaskDraw 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)
47Journal and Push Yourself Outcome 18: Describe the structure and purpose of joints in the skeletal system
