00:10 Breath in, breathing out! That’s what I say throughout!
00:14 Breath in, breathing out! That’s what I say throughout!
00:23 Oh, so you’ve been watching me work out? Eh?
00:27 Rather breathe in.. and breathe out.
00:30 Ooooh. This is tiring.
00:33 So anyway, why don’t we talk about Breathing today?
00:37 Still can’t get a hint?
00:39 Well, today we’ll talk about the Human Respiratory system!
00:44 Zoom in!
00:46 Alright, do this, right now.
00:49 I am watching you.
00:50 Just start running wherever you are
00:53 Run, run, run, run, run! Now stop!
00:59 Isn’t your breathing heavy?
01:01 Well, that’s because right now your body needs more oxygen to breathe!
01:07 And you get oxygen from the air around you.
01:11 Without oxygen, you’d be like a car without fuel..
01:15 ..a water-less pool and wouldn’t that be uncool?
01:20 One of the major reasons why you’re alive is Oxygen!
01:25 So take a deep breath in.
01:31 When you breathe in, you take in oxygen present in the air.
01:36 The air then passes through your nostrils.
01:39 There are tiny hairs present in your nostrils..
01:42 ..that obstruct all the dust particles
01:48 Then the air travels through the windpipe, also called the Trachea..
01:54 ..which filters the air inhaled.
01:57 The Trachea branches out to two tubes called Bronchi.
02:02 Where tiny hair called Cilia move back and forth moving the mucus inside.
02:08 The Mucus is a sticky substance that collects germs and other particles..
02:14 ..that might harm the lungs.
02:16 The Bronchi then carry air into each lung.
02:20 The right has three lobes whereas, the left lung has two lobes.
02:27 The left lung is slightly smaller in size to give space to the heart.
02:32 These lobes are filled with small and spongy air sacs called alveoli..
02:39 ..where the exchange of oxygen and carbon dioxide happens
02:44 It is here, the blood picks up oxygen and lets go off carbon dioxide.
02:50 Just beneath the lungs, there’s a dome-shaped muscle called Diaphragm..
02:56 ..that contracts when you breathe in and expands when you breathe out.
03:02 It also separates the chest cavity from the abdominal cavity.
03:08 TRIVIA TIME!
03:12 The lungs are the only organs that can float on water.
03:16 A person breathes approximately 20,000 times in one day.
03:21 So friends! Didn’t you just gasp and grasp all the facts?
03:28 Tune in next time for more fun facts.
03:32 This is me zooming out!
