  [hs height=”450″ theme=”3d-dark” buttons=”true” ] 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! [/hs][/vc_column_text][vc_separator][vc_column_text]
