Health: Germs And The Space Visitors (1971)

weird huh look [Music] wow what is it let's go closer [Music] Welcome Friends must be a space man why don't you come in should we have you ever been inside a spaceship come on I want to look okay okay lck link excellent just stand right there [Applause] [Music] welcome bleck bleck hi I'm bleck and I'm double gleck gleck gleck gleck we're from the galaxy of Quadro CIA and we need your help us our planet is getting too close to its Sun someday it will burn up that's why we have to find a new one to live on we'll show you around let's go well it may not be safe for us you see we are built quite differently from you and on our last visit here we found some things in your air water and soil that might hurt us microbes they are tiny little living things that you can't see unless you look through a microscope take a look the microscope makes the microbes look much bigger than they really are wow microbes huh you mean these things are all over out there one's very much like them all over everything on the earth even on your skin and clothes it would take about 5,000 of the biggest microbes to make a line 1 in Long can they hurt some can hurt you they're too small to bite but they can make you sick there are microbes that hurt you and microbes that don't microbes that hurt you are called germs all these are germs there are three main types of germs the biggest germs are protozoa protozoa are actually tiny little animals now these germs are the second type they're called bacteria they're smaller than protozoa bacteria are tiny plants the third type of germs are viruses they're the tiniest of all so germs are microbes that can make me sick if a lot of germs get inside you they can make you sick how do they do that well we've studied your human bodies and found them to be made up of cells uh like a big chimney is made up of tiny little brick cells are the tiny building blocks that make up your body and your cells are so tiny that you can't see them without a microscope why uh they're hardly any bigger than germs look germs can kill your little cells see those little white bars they are germs that got ins inside a body this is a cell like all the millions of little cells that make up your body and they're trying to get inside the cell they got in and they are hurting the cell so if enough germs get inside enough of your cells you'll feel sick look these bacteria inside you can give you a very sore throat strep throat it's called did you ever have a strep throat I did take a look at these these will make you sick too here's the virus that causes colds how do these germs get inside us they get in through an opening in your body uh like your mouth germs can also ride in on specks of dust when you breathe and look they can enter through your mouth on the liquids you drink we saw you drink that water Yesterday by our gab beam they can also get into your body through a cut or a scratch but I've got a cut and I'm not sick yeah if there are germs all over everything even in the air we breathe how come we're not always sick we don't know we were hoping that you could help us find out why and that's why we wanted you to come in here we want to examine you in our glycos Scope when it looks inside your body it tells us what's happening and shows us a picture here wow can I be first okay now we'll find out how your body defends itself against all those germs you have here on Earth bye so long first I'd like to take a good look at that human skin of his my goodness gleck it's like a protective glove I don't see how any germs could get through that I'll shoot a few germs into the skin and see nope the germs can't get through the skin let's take a look inside his mouth okay aha his mouth and throat are wet and slimy and germs are try to get in that way get trapped look here there are tiny hairlike things they're called cyia and they're in his nose and other air passages look the CIA moving waves and carry the germs right back out what I like to see is what's happening to the cut on Ross's arm looks like some germs are getting in through that break in the skin covering what are those big things those are white blood cells they're eating the germs right the white blood cells are attacking and killing the CHMS look what the GLE is saying the glecos scope is saying that the white blood cells have helpers they're called antibodies antibodies help the white blood cells let's see ah those white blobs are white blood cells and the black dots are germs uh the little black rods are the antibodies his body is formed see how they attach to the germs and make them Clump together now the white blood cells can kill them then the antibodies are left behind to help if they're Ever Needed again so that's how your body fights off germs look what the glecos scope is saying double Gleek this is what triple GLE told us we might find your Earth doctors can help you make your own antibodies by giving you shots I'm sure both of you have had shots wow that's some defenses it's a good system but not foolproof there are three ways germs can make you humans sick first if you're overwhelmed by a huge invasion of so many germs that your defenses can't stop them all and second if your defenses are weakened like when you're tired third if you haven't yet built any antibodies to help the white blood cells but you can help your body fight germs keeping clean like washing your hands before eating that would wash away Le armies of germs by getting plenty of sleep so your body will be fresh to fight any germs that do get in and when you get cuts and scratches clean them and put disinfectant on them that kills germs that might try to get in that way good wholesome food gives your body the energy it needs to defend against germs don't put anything in your mouth but food no fingers no pen they might have a lot of germs on them and finally cover your nose and mouth whenever you sneeze or cough that helps to keep the germs from going to other people and making them sick I'm afraid we wouldn't be able to stay alive here on your planet it's the germs and all those defenses that you have against germs we don't have any of them well thanks a lot for helping us we'll be going now step right over here boys gee I sure wish you could stay sorry but but we can't bye Sal bye [Applause] [Music] no
