Hi I am O2 ,you can call

me oxygen, and I will be your guide today.

I advise you keep all feet

and hands inside the ride at all times.


Respiratory intro l.jpg
Respiratory Intro

You may be asking, what is the Respiratory system? Well, the Respiratory system is the system that helps you breath in and out, so oxygen (02) can be pumped through your body and carbon dioxide (CO2) can be removed from the blood stream. You must remember that the Respiratory system is made up of many different organs.


Where are we l.jpg
Where are we?

Nasal Passage



Bronchi Tubes

The Trachea is held open by partial rings of cartilage.

Alveoli (air-sacs)

Thin-walled blood vessels called capillaries

Bronchioles pass air to and from your alveoli.

Very thin cells line the alveoli so that O2 and CO2 can pass in and out of the blood.

Here We Go!!!

Welcome l.jpg

Now we will begin our tour.

Welcome to…


The Respiratory System


The nose and mouth l.jpg

The Nose and Mouth

This is where it all begins.

This is where the oxygen first

enters your body and also where

Carbon Dioxide leaves.


The nose and mouth10 l.jpg
The Nose and Mouth

When the air comes into your nose it gets

filtered by tiny hairs and it is moistened by the

mucus that is in your nose.

Your sinuses also help out with your

Respiratory System. They help to moisten

and heat the air that you breath.

Air can also get into your body through your

mouth/oral cavity but air is not filtered as

much when it enters in through your mouth.

Very thin cells line the alveoli so that O2 and CO2 can pass in and out of the blood.

Where are We?

We are here.


The pharynx and trachea l.jpg

The Pharynx and Trachea

Next we will head down to your pharynx

(throat) and your trachea (windpipe).

This is where the air passes from your

nose to your bronchi tubes and lungs.


The pharynx and trachea14 l.jpg





The Pharynx and Trachea

Your pharynx (throat) gathers air after it passes

through your nose and then the air is passed down to

your trachea (windpipe).

Your trachea is held open by “incomplete rings

of cartilage.” Without these rings your trachea

might close off and air would not be able to get

to and from your lungs.

Bronchi Tubes

The Trachea is held open by partial rings of cartilage.

Alveoli (air-sacs)

Thin-walled blood vessels called capillaries

Bronchioles pass air to and from your alveoli.

Very thin cells line the alveoli so that O2 and CO2 can pass in and out of the blood.

Where are We?

We are here.


The bronchi tubes and bronchiole intro l.jpg

The Bronchi Tubes and Bronchiole Intro

Your trachea (windpipe) splits up into

two bronchi tubes. These two tubes keep

splitting up and form your bronchiole.


The bronchi tubes and bronchiole l.jpg
The Bronchi Tubes and Bronchiole

These bronchi tubes split up, like

tree branches, and get smaller and smaller

inside your lungs.

The air flows past your bronchi tubes

and into your bronchiole. These tubes

keep getting smaller and smaller until they

finally end with small air sacs (called alveoli).

But we will go there later…

Now we will head over to the

alveoli and what happens when the

air finally makes it down there.


The alveoli and capillary network21 l.jpg
The Alveoli and Capillary Network

Your alveoli are tiny air sacs

that fill up with air/oxygen when you

breath in.

Your alveoli are surrounded by

many tiny blood vessels called


The walls of your alveoli (and capillaries) are

so thin that the oxygen or carbon dioxide can

pass through them, traveling right into, or

out of your blood stream.

Diffusion l.jpg


Carbon Dioxide

Oxygen diffuses through the membrane into the blood stream. Carbon Dioxide diffuses through the membrane and enters the alveolus.

* A specialized thin layer of skin that oxygen and carbon dioxide can pass through.


Intro to diaphragm l.jpg
Intro to Diaphragm

Now we will look at the Diaphragm. You might be wondering, what does the Diaphragm do? The Diaphragm is an important factor in breathing.


Diaphragm experiment l.jpg
Diaphragm Experiment

Here is an experiment that you can try.


Experiment instructions l.jpg

1st you need a bottle that you can sacrifice to

cut up.

Experiment Instructions

2nd you cut the bottom of the bottle and put a big balloon on the bottom.

3rd get a rubber cork ( make sure it blocks the hole)and put a hole through it ( top to bottom). Insert a thin tube into the cork and place a balloon on the bottom of the tube.

4th make sure the thing is airtight.


Respiratory overview review l.jpg


Air Passing over the mucus membrane of the nasal cavity is moistened, warmed, and filtered

Inside the lungs the Bronchi branch into small tubes called bronchioles

Respiratory Overview Review

The Pharynx, or throat, is located where passages from the nose and mouth came together.

At the end of the bronchioles are bunches of alveoli, air sacs, arranged like grapes on a stem

Air enters the trachea, or wind pipe which leads to and from the lungs

If one lobe is injured or diseased, the other lobes may be able to function normally

The trachea divides into two tubes called bronchi


Fun facts l.jpg
Fun Facts

* At rest, the body takes in and breathes out about 10 liters of air each minute.

* The right lung is slightly larger than the left.

* The highest recorded "sneeze speed" is 165 km per hour.

* The surface area of the lungs is roughly the same size as a tennis court.

* The capillaries in the lungs would extend 1,600 kilometers if placed end to end.

* We lose half a liter of water a day through breathing. This is the water vapor we see when we breathe onto glass.

* A person at rest usually breathes between 12 and 15 times a minute.

* The breathing rate is faster in children and women than in men.

Key words l.jpg
Key Words

  • Respiratory System- The group of organs in your body that are responsible for taking in Oxygen and breathing out the Carbon Dioxide which is the waste product of cellular respiration.

  • Oxygen-The gas that your body needs to work and function.

  • Carbon Dioxide- The waste product (gas) that is produced through respiration of people and animals.

  • Nose/Nasal Cavity- Where Oxygen first enters your body. Tiny hairs help filter the air and air is moistened and heated by your nose. Your Nose leads into your Nasal Cavity.

  • Mouth/Oral Cavity- Oxygen/air can also enter through your Mouth but it is not filtered. Your Mouth opens up into your Oral Cavity.

  • Sinus- A cavity in the bones of your skull that helps moisten and heat the air that you breath.

  • Pharynx/Throat- Gathers air from your Nasal and Oral Cavities and passes it to your Trachea.

  • Trachea/Windpipe- A tube like pathway that connects your throat to your Bronchi Tubes and lungs. Air passes through it when it travels from the Pharynx to the Bronchi Tubes.

Key words cont l.jpg
Key Words Cont.

  • Bronchi Tubes- Each tube (one per lung) splits up into many smaller tubes called Bronchiole, like branches on a tree.

  • Bronchiole- Keep splitting up until they reach your Alveoli.

  • Respiratory Bronchiole- The air-tubes that are actually connected to the Alveoli.

  • Alveolar Duct- The final tube, which is part of the Alveoli, that leads to the air-sacs.

  • Alveolar Sac- Where the chemical change takes place and where blood cells pick up oxygen and drop off carbon dioxide.

  • Alveoli- Tiny air-sacs at the end of your Alveolar Duct. They fill up with Oxygen and are surrounded by Capillaries.

  • Capillaries- Tiny blood streams (around one cell wide) that surround your Alveoli. They take Oxygen out of our Lungs and replace it with Carbon Dioxide, which you later breath out.

  • Diaphragm- The muscle membrane that helps you breath in and out by changing the pressure in your chest cavity.

The Circulatory System

Circulatory System Created by

Hannah Redlich and Joe Zalan

Caltex American School Duri, Indonesia

Introduction l.jpg

  • The Circulatory System is the main cooling and transportation system for the human body

  • The body has about 5 liters of blood continuously traveling through it by way of the Circulatory System

  • In the Circulatory System, the heart, lungs, and blood vessels have to work together

  • The Circulatory System has three different parts: pulmonary circulation (lungs), coronary circulation (heart), and systemic circulation, (the rest of the system’s processes).

The heart l.jpg
The Heart

This organ is what pumps oxygen rich blood, nutrients, hormones, and the other things your body needs to maintain your health, to your organs and tissues.

The pulmonary veins you see on the right side of the diagram come from your lungs, where the blood cells collect oxygen. It’s then pumped out to the rest of the body through the Aorta (Top).

All of the blue sections show blood cells carrying waste, (C02) moving back to the lungs (where the C02 will be replaced by oxygen) through the Pulmonary Artery (Top, blue)

Pulmonary Artery

(Superior Vena Cava) From the Body

(Aortic Artery) To the body

Pulmonary Veins

Valves: (tricuspid valve semilunar (pulmonary) valve, bicuspid (mitral) valve, and the semilunar (aortic) valve

(Inferior Vena Cava) From the Body

By The Way…

Whenever the blood is pumped from one section of the heart another a valve closes behind it preventing the blood from moving backwards.

Blood flow through heart l.jpg
Blood Flow through Heart

  • Blood from the body travels into the right atrium, moves into the right ventricle, and is finally pushed into lungs in the pulmonary arteries

  • The blood then picks up oxygen and travels back to the heart into the left atrium through the pulmonary veins

  • The blood then travels through the to the Left Ventricle and exits to the body through the Aorta…

Left Atrium

Right Atrium

Blood flow to arms l.jpg
Blood Flow to Arms

  • Oxygen rich blood leaves the heart and travels through arteries

  • In the capillaries the oxygen and food is given to the body’s cells

  • The blood finally travels back through veins to the heart to pick up oxygen




Path to the exchange l.jpg

A red blood cell then travels from the heart through arteries that eventually branch into the body’s vast system of capillaries (microscopic blood vessels which connect arteries and veins), they eventually lead to…

Ulnar Artery

Iliac Artery

The exchange l.jpg


When the itty bitty teeny tiny red blood cells pass the desired tissue they……………………………….

Oxy-Rich Blood Cell


The Exchange

The oxygen the blood cells are carrying is given to the body’s tissue.


And the CO2 (waste) from the tissue is given to the same blood cell to be exhaled.

Oxy-Poor Blood Cell

Technically the Hemoglobin in the blood (a substance full of iron) attracts oxygen from the lungs. The red blood cell then carries it to the desired tissue. Because this tissue has a high CO2 count the hemoglobin lets go of its oxygen and collects the carbon dioxide. You see the hemoglobin has an affinity for whichever gas has a greater count. Because the tissue has a large amount of built up waste (CO2) the hemoglobin attracts it and then replaces it with oxygen, and vise versa in the lungs.

How It Works…

Now lets travel to the legs!!!

Blood flow to legs l.jpg
Blood Flow to Legs


  • Approximately 500 ml of blood moves from the heart and lungs down to the legs when a person stands up after lying down

  • The oxygen rich blood cells then travel through the capillaries where yet another…

Gas exchange occurs l.jpg

Don’t forget that the Hemoglobin in the blood cells let go of the cell’s oxygen because of the large CO2 (waste) count in the tissue.

Conclusion l.jpg

As you have learned (Hopefully) the Circulatory System is one of the most important systems in the human body…

It is the only reason you’re still alive today…

and you can attribute the cooling down, feeding of and protection of your body to it.

So the next time you bust open your leg skateboarding you can thank your Circulatory System for patching you up.
