The respiratory system is more than just important - it’s vital to our survival! Without it, we wouldn’t be able to breathe, and we all know that we’ll die if we don’t breathe.
What Is The Respiratory System?
The respiratory system is what introduces oxygen to our system and allows us to breathe out carbon dioxide.
In mammals - humans included - the respiratory system consists of the lungs, airways, and respiratory muscles. Those are the bright blue parts on the diagram on the right.
What Does The Respiratory System Do?
The respiratory system makes sure that our blood stays oxygenated, and gets rid of the carbon dioxide. Oxygenated blood is pumped through our system by arteries, and deoxygenated blood is carried by veins.
The respiratory system is constantly at work - we’re not usually conscious of our breathing, but we’re always doing it. Without a respiratory system, we’d be dead.
It also plays an important part in speech. Just try holding your breath and saying something - you won’t be able to do it!
The movement of air in our larynx, pharynx and mouth is what makes a sound when we talk. If the air isn’t moving, we can’t make any noise!
Some animals, like dogs, also use the respiratory system in order to keep cool. They do this by panting.
