Respiratory System Song

Science Songs

Every breath in gives oxygen
For our whole body

Each breath out provides carbon dioxide
Two gases exchanging

Each breath in your mouth or nose in goes oxygen
Past the pharynx, past the flap of epiglottis
Your voice box larynx, then the trachea divides
Air enters the lungs into the primary bronchi

In the bronchial tree
Oxygen keeps on traveling, see?
Deep in the bronchioles
To air cluster sacs called

Sacs called alveoli
With capillaries on the outside
Blood picks up the oxygen
Drops off its CO2 waste, then

Two gases exchange in

Lungs, they are two gray organs, spongy
Oxygen, respiratory
For the purpose of exchanging gases through your

Blood, takes the oxygen carries
From your lungs through your body
Then releases waste of CO2 gases breathe out

Inside of an alveolus
Where the exchange of gases happens
Each molecule of oxygen
Diffuses into a capillary, enters the blood
From the plasma to the RBC
That’s the red blood cells, oxygen binding
With heme part of the hemoglobin protein
To make oxyhemoglobin complete

Then the carbon dioxide
Blood drops off a waste gas
Goes the other direction
From the blood, alveoli, back up to the bronchi
Travel up through the trachea
Larynx, pharynx then the final area
Exiting nasal or oral cavity
All of that happens every time you breathe

Your diaphragm helps you breathe
Right below your lungs, muscle underneath
When you breathe in, it contracts
Moves down so your lungs can expand

Your rib bones protecting
Intercostal muscles in between each
Also helps lungs expand and condense
Helpful these muscles surrounding

Two gases exchange in

Lungs, they are two gray organs, spongy
Oxygen, respiratory
For the purpose of exchanging gases through your

Blood, takes the oxygen carries
From your lungs through your body
Then releases waste of CO2 gases breathe out
