Body Works Circulation, Excretion and the Skeleton D. Patterson
Lesson 12 Outcome 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 dioxide The name of the pigment that makes red blood cells appear red is called:
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! SkinLungs 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. 206 in the body 26 in a foot
Task Visit 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: What are the purposes of the skeleton? GET READY TO WRITE!!
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)
Journal and Push Yourself Outcome 18: Describe the structure and purpose of joints in the skeletal system
