1.1 The human respiratory system

Continued

2 Touch the lungs.
What do they feel like when you push them? Can you suggest why they feel like

this? (Look at the diagram of the human respiratory system to help you.)
3 Look at the tube that carries air down into the lungs.
a What is the name of this tube?
b Feel the tube. What does it feel like?
c Follow the tube towards the lungs. Can you find where it divides into two?

What are the names of these two tubes?
d Now look at the top of the big tube, where it is wider.
What is the name of this wide part? What is its function?

The diagram of the respiratory system includes a lot of new words.
How are you going to learn this diagram and all of its labels?

Remember that, in a test, the diagram might not be exactly the
same as this one.

Activity 1.1.1

What does the larynx do?
Hold the fingertips of one hand against your larynx (voicebox).

Keep your lips together, and make a loud humming sound.

Can you feel the larynx vibrating?

Your larynx contains your vocal cords. These are bands of muscle that stretch across
your larynx. You can think of them as being like guitar strings. When your vocal cords
vibrate, they make a sound.

Now make a higher-pitched humming sound. Then try a really deep pitched sound.

Can you feel the larynx changing when you make the different sounds?

Summary checklist

I can name the parts of the respiratory system, and identify them on a diagram.
I can list the organs that air passes through, as it moves into and out of the
lungs.
