  • Breath in, breathing out! That's what I say throughout!

  • Breath in, breathing out! That's what I say throughout!

  • Oh, so you've been watching me work out? Eh?

  • Rather breathe in.. and breathe out.

  • Ooooh. This is tiring.

  • So anyways, why don't we talk about Breathing today?

  • Still can't get a hint?

  • Well, today we'll talk about the Human Respiratory system!

  • Zoom in!

  • Alright, do this, right now.

  • I am watching you.

  • Just start running wherever you are

  • Run, run, run, run, run! Now stop!

  • Isn't your breathing heavy?

  • Well, that's because right now your body needs more oxygen to breathe!

  • And you get oxygen from the air around you.

  • Without oxygen, you'd be like a car without fuel..

  • ..a water-less pool and wouldn't that be uncool?

  • One of the major reasons why you're alive is Oxygen!

  • So take a deep breath in.

  • When you breath in, you take in oxygen present in the air.

  • The air then passes through your nostrils.

  • There are tiny hair present in your nostrils..

  • ..that obstruct all the dust particles

  • Then the air travels through the windpipe, also called the Trachea..

  • ..which filters the air inhaled.

  • The Trachea branches out to two tubes called Bronchi.

  • Where tiny hair called Cilia move back and forth moving the mucus inside.

  • The Mucus is a sticky substance that collects germs and other particles..

  • ..that might harm the lungs.

  • The Bronchi then carry air into each lung.

  • The right has three lobes whereas, the left lung has two lobes.

  • The left lung is slightly smaller in size to give space to the heart.

  • These lobes are filled with small and spongy air sacs called alveoli..

  • ..where the exchange of oxygen and carbon dioxide happens

  • It is here, the blood picks up oxygen and lets go off carbon dioxide.

  • Just beneath the lungs, there's a dome-shaped muscle called Diaphragm..

  • ..that contracts when you breathe in and expands when you breathe out.

  • It also separates the chest cavity from the abdominal cavity.


  • The lungs are the only organs that can float on water.

  • A person breathes approximately 20,000 times in one day.

  • So friends! Didn't you just gasp and grasp all the facts?

  • Tune in next time for more fun facts.

  • This is me zooming out!

Breath in, breathing out! That's what I say throughout!
