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.
00:27 And that’s why,…
00:30 We’ll talk about Virus!
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…
03:51 Until next time, this is me zooming out!
03:59 Oh no!
