Hey I am Doc Neuron and I would love to welcome you to the 

wonderful world of science. Now you all must be thinking that 

this is an awfully long boring book about science but no! You're 

wrong. 

This is a fabulous, exciting and super scrumptious book with 

loads of info, that even teenagers can enjoy.

I am the Doc

So we all watch action movies right? So lets just say we're watching Guardians of the 

Galaxy and we are up to the part where they are escaping the prison and Rocket the 

Raccoon was so busy playing with the stupid fake leg, which has nothing to do with the plan 

but he thinks it's funny and everyone is staring... oh you're still here, I'm getting carried 

away! 

Anyway lets say he presses a button that releases a deadly gas that knocks out everyone 

except robots (Rocket is a robot). Rocket is stuck with sleeping crew mates and needs to 

wake them up - fast! Nothing seems to work not even water, so to get them up he needs a 

better understanding of how the Respiratory System works and this is what he finds...

Q1- What is the role of the Respiratory System?

Your lungs play a special part in keeping you alive. They take in oxygen that travels from 

your nose into your lungs where red blood cells pumped from the heart collect the oxygen 

molecules and take it to every part of your body. 

Every muscle, tissue, organ and cell all need oxygen, so the Respiratory system’s job is to 

get your blood rich in oxygen. This keeps us alive, happy and healthy. It is very important 

for survival and we inhale and exhale to get oxygen and carbon dioxide in and out of our 

body.

appear on every 

page just for fun 

just to make sure 

your learning :)

Q2- What are the organs and parts that make up the Respiratory System?

Our Respiratory System is made up of organs, bones and muscle tissue. These parts work 

together to form our Repository System.

The parts include:

Nasal cavity- It is basically a little space inside the nose which is covered in mucus (snot) 

and little hairs.

Oral cavity- Also known as the mouth 

Pharynx- Also known as the throat.

Tongue- A pinky coloured muscle covered in taste buds

Epiglottis- A stretchy flap of tissue   that covers the windpipe

Trachea- Is the windpipe that is a 5 inch tube

Larynx- Is the voice box

Pleura- A thin barrier around the lungs and on the inner walls in the chest.

Bronchus- Located at the end of the trachea and it divides the windpipe into the lungs. 

We also have the Bronchioles, which contain millions of air sacs called Alveoli. Alveoli are the 

small sacs in the lungs that exchange oxygen with the blood.

Right lung- A spongy, stretchy muscle that expands 

when air is taken in.

Left lung- A spongy, stretchy muscle that expands 

when air is taken in.

Diaphragm- Is a sheet of muscles that lies across 

the bottom of the chest cavity.

Q3-What is the function of each part of the system?

There are three major parts that make up our repository system. It is made up of the 

Airways, the Lungs and the Respiratory Muscles. These major parts and other minor parts 

work together to help us inhale and get oxygen into our body and in our blood stream and 

exhale to release carbon dioxide. The airway consists of the nose (Nasal Cavity), mouth (Oral 

Cavity), Pharynx, Larynx, Trachea and Bronchi. Each piece has a different function to make 

the Respiratory System successfully work. 

The Nasal Cavity- Is the hollow space   and its function is to warm, moisturise, and filter air 

entering the body before it reaches the lungs. The surface is covered in hairs (cilia) and 

mucus (yuck!). These hairs and mucus work together to complete these steps.

Oral Cavity- The mouth supplements the nasal cavity. The usual breathing takes place in 

the Nasal Cavity but the mouth supplements its function when you can’t use it or is very 

difficult to breath through the nose.

Pharynx- The pharynx, or throat, is the passageway leading from the mouth and nose to 

the Esophagus and Larynx. It allows air to travel to and from the Trachea, or Windpipe, 

during respiration.

Tongue- It is part of the Oral Cavity and doesn't really play an important part in the 

Respiratory System, but is used more in the Digestive System which is... wait we're talking 

about the Respiratory System so never mind, lets just keep going.

Epiglottis-  The Epiglottis is a small flap of elastic cartilages that acts as a transition 

between the Trachea and Esophagus. The function of the Epiglottis is to ensure that air 

passes into the Trachea by covering the opening of the Esophagus.

Trachea- The function of the Windpipe or Trachea is to allow air passage from your Nasal 

and Oral Cavity to your lungs. It allows air rich in oxygen to travel down when you inhale 

and travel up when you exhale carbon dioxide. 

Larynx- The Larynx's function consists of a valve (barrier), which stops the air from 

escaping the lungs. It also prevents foreign substances from entering the lungs.

Pleura- It is the slick wet barrier in the inner walls and around the lungs that creates a 

thick surface that prevent the lungs and the chest wall to contact one another with minimal 

friction.

Bronchus- The bronchus are extensions to the Windpipe that travel air to and from the 

lungs. It is like a highway, oxygen going to the lungs and carbon dioxide leaving them, 

through the windpipe.

Lungs- Each day we breathe about 20,000 times. The function of the lungs is to take in 

oxygen and filter them into the bloodstream where red blood cells take the oxygen 

molecules to every part of your body. This process happens when you inhale. When you 

exhale carbon dioxide is taken by the blood cells back into the lungs where it is released 

back into the air. This process takes milliseconds and is faster than blinking. Crazy right?  

Even a scientist with all the cool equipment can't tell the exact speed blood travels around 

the entire body.

Diaphragm- The function of the diaphragm is to get rid of carbon dioxide out of your 

lungs and pull the oxygen into your lungs. The breathing takes place when the diaphragm 

contracts and relaxes.
