  [hs height=”450″ theme=”3d-dark” buttons=”true” ] 00:06 Hey friends, I’m not feeling too well today. 00:11 I think I have a cold… 00:16 Well, I guess it is a good time to tell you about what causes cold,.. 00:21 ..and many other such diseases. 00:25 Sorry. 00:27 And that’s why,… 00:30 We’ll talk about Virus! 00:33 ZooZoooo..ZOOOOOMINNNNN! 00:38 You know that a bacterium is a very tiny organism, right? 00:43 Well, a virus is so small, that it is invisible to even a bacterium. 00:50 This is how it is able to infect the tiny bacterium and the cells in our bodies 00:57 Unlike the bacterium, the virus has no cytoplasm. 01:01 Or a nucleus or anything resembling a cell. 01:07 It has a very basic structure of the DNA.. 01:10 ..covered by an outer protein shell and some fats. 01:15 That’s why viruses cant even be considered organisms at all. 01:20 They are not actually living. 01:22 They float around like debris in space, waiting to contact a host. 01:28 And only once they enter a host, can they reproduce! 01:35 This is where the true terror of Viruses is seen! 01:40 Once inside, these little fellas hijack the cells of the organism. 01:45 By entering through the cell membrane. 01:49 Once they do, the virus takes over the protein building structures of the host cell.. 01:54 ..and forces them to replicate the virus instead. 01:59 The poor cell unknowingly begins manufacturing an army of the virus.. 02:05 ..till the entire cell is infected! 02:09 This poor mindless slave cell does this till it explodes! 02:15 Releasing all the virus to infect the nearby cells.. 02:19 And that’s how an infection spreads. 02:23 That’s why I got sick. 02:26 But don’t worry, your bodies are super smart when it comes to saving you. 02:35 Every time we fall ill with a virus,.. 02:38 ..the body makes a special cell called a Memory Cell. 02:43 This cell stores all the information about the virus and how it was defeated.. 02:50 ..so that the next time the virus attacks, your body’s defense is ready to destroy it! 02:58 TRIVIA TIME! 03:00 Did you know that even antibiotics don’t work on viruses? 03:06 Because antibiotics are designed to fight bacteria! 03:12 In our body, the most common viruses are actually bacteriophages.. 03:18 ..that infect and destroy bacteria! 03:26 I think I have a cold again. 03:29 Well kids, before I go,.. 03:32 ..what’s the common virus in our body that destroys bacteria? 03:40 And here’s hoping I feel better soon. 03:44 So that I can keep bringing you such fun and interesting… 03:50 ..facts. 03:51 Until next time, this is me zooming out! 03:59 Oh no! 04:01 Hey kids, you liked my videos didn’t you? 04:05 Before you go, don’t forget to click on the subscribe button and the bell. 04:10 So you won’t miss out on my latest videos. 04:15 See you.
