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

• http://www.nobelprize.org/educational/medicine/bloodtypinggame/game/index.html

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!

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:

• 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)
