The circulatory system

Lesson 1:

Organs of the human body

Starter:

Definition of an organ Organs are structures in the human body made of several types

of tissue and therefore several types of cells that have to fulfil a

specific function.

Two minutes: write down as many organs of the

human body as you know.

Have you mentioned any of these?

Which one is which? Try to label

them

(Help: Eyes, heart, kidneys, lungs,

ear, brain, intestines, gall bladder,

stomach, uterus, nose, pancreas,

skin - careful, not all are needed)

Here are some major organs:

Why do we need these organs? What is their function?

Find out here:

BBC bitesize Introduction to the major organs of the human body

After having learned about the different jobs of the organs, try this

matching game on the next slide

(if you have scissors, cut out the functions and organs and stick

them next to each other.)

This organ removes toxins from the blood and makes blood

This is where oxygen gets into the blood. Carbon dioxide leaves the blood here.

This is where the body absorbs food and water into the blood.

This pumps blood to all parts of the body.

This control most of the things your body can do.

These help the body to get rid of waste substances. They make urine.

This mixes food with acid and gastric juices. It starts to break down food.

Have you got it

correctly?

Check carefully:

Answers:

Where can all these

important organs be

found in the human

body? Have a go and

draw them where you

think they should go:

Answers: Check carefully!

Is your heart also in

the middle?

Bonus question:

How is your heart

protected?

How is your brain

protected?

Odd one Out

How many points can you make?

EXTENSION:

Research another organ of the body and add information to the organs

you have already looked at.

Bonus question: brain – skull; heart – rib cage

Lesson 2:

Understand the importance of organs

Task - write an persuasive argument/give a speech:

I am the most important organ in the human body

How to do it:

Use your notes from yesterday. Which organ do you think is the most important one

and why?

What language should you use?

• Formal, scientific

• Grammatical features: subordinate conjunctions as they allow you to make comparisons

(e.g. While some would argue . . . , Whereas the ____ is needed ____, one could not . . . . )

• adverbials such as however, on the other hand, . . . )

• Modal verbs: One could say . . . , Others might suggest . . . , You must consider, one would

• compare yours to the other organs and refer back to their function

• structure your argument: introduction, points, possibly some statistics

•Some ideas are on the next slide:

I am the most important organ in the human body

You could start like this:

(introduction)

The human body is host to range of different organs which all serve its survival and well-being. Each

and one of them have their different functions – important functions . however I am of the opinion that I,

the _________ , am the most important one.

(points)

Consider a life without me; it would ___________________. One ____ could not __

Other might argue that without a _____________ is equally impossible. However, ____________

You might even sneak in a reference to the Ancient Egyptians. . . )

Already the Ancient Egyptian thought that __________ and therefore __________.

(conclusion)

Consider all the different points, I imagine a life without me ____________________

Don’t worry – you can’t be wrong. Just make sure you explain the reason for your choice.

HAVE A BIT OF FUN. I look forward to reading (or hearing) your argument!

Lesson 3:

Understand the Circulatory

System

Starter: The human body has many organ systems – these are some of them:

skeletal system circulatory system muscular system digestive system

Can you match them up correctly?

Educational link: The circulatory system 2 This one contains more detailed information

The circulatory system 1 This is a good starting point.

To learn more about circulatory system, here are some resources

watch carefully

As they speak quite quickly in the video, it recommend to read through the text on the

next slide

1 Why is it called ‘circulatory’ system?

2. What is the function of the circulatory system?

3. What pumps the heart around your body?

4. What is it that your body (cells) needs that the blood delivers?

5. How long does it take for one blood cell to go around the body?

6. How does your body get rid of the unwanted carbon dioxide?

7. What are the different parts of the circulatory system?

8. What are arteries?

9. What are veins?

10. What are capillaries?

11. How many loops (circles) are there in the circulatory system?

12. Explain the two loops of the circulatory system:

Lesson 4:

To understand the heart

Starter:

Study the next slides to

find out more about the

amazing heart and its

parts . . .

Task: Fill in this diagram (print or sketch); use colours according to the key. Extension: Add more detail to this drawing by using the information you have learnt about the heart . If you can, send in your diagram to your teacher’s e-mail address.

FUN FACTS

Lesson 5:

Apply your knowledge

This is how it works:

Print out the question cards (with answers) or write each question on a

piece of paper.

Choose a board game that uses a die and counters.

Place the cards upside down on a pile.

Find a person to play with.

Roll the die – the person next to you picks up a card and reads the

question out to you. If you get the answer correctly, move your counter

forward according to your die. If not, stay put (or go backwards – agree on

rules).

The next person has a turn.

Once all the cards are used, reshuffle and reuse.

There are some spare cards to write your won questions too.

The person wins, who is first over the finishing line. HAVE FUN

There are some spare

cards to write your won

questions too.
