are and why it's so important to follow them. the d w. these places in europe are smashing the record step into a little bit venture. it's the treasure map for modern globetrotters. discover some of us record breaking site on drawbacks youtube and now also in book form, the 9th is thrilled with danger. and that's why we protect ourselves where we can we install antivirus software on our computers and non systems in our homes to prevent break ins. and if there's a fire, we called emergency services. and output is also protect themselves from infection . the means system is a complex network of organs,

cells and messenger substances. how it works, coming up on in good shape. the skin is the immune systems, 1st line of defense. it protects the body from external passages. it stick it in some places and then all those gone off one sort of how, how much is our dead skin cells that form a physical barrier against invading organisms. so keep that totally not on the mouth or the eyes, that would cloud your vision and stop you being able to taste involve males making . so what we have there are mucous membrane. there is spirit tree, and urinary tract also have mucous membranes. the mucus laya helps expel pathogens to slime. hoyt,

i think some units or the mucus membranes are composed of cells that form a physical barrier. and, but these are washed with a lot of saliva and other fluids here by these have many components. and then that haven't antiviral or anti bacterial effect until the of odd auntie back to the field. the intestine is to be a mean systems grand central station, northern how far immune cells are locations in the intestinal world. this is when most defense reactions against pathogens take place. as well as the immune system and the god there is of course the micro biome, all of the microbes that are found there because this is, they are habitat. other bacteria can't easily established themselves. there's their fault office, there's no room for that. i'm from the time slots when the bone marrow is also concept gaming system. it's located inside the boons. this is when

most immune cells are produced. they perform various tasks, not mocks. the bone marrow basically provides the so precursors the which mature in the fight against invaders, and then produce antibodies listening ones on, on to crop up here. the time is a small gland under the breastbone, a specialized organ that acts as a kind of school for special like blood cells called t cells. white blood cells travel from the bone marrow to the timeless and mature that pets are for this simulation by yourself. cool is quite yes, correct tools in 1st grade, the teacher teaches the t cell students what they need to respond to was still they again as of in mine on the end, they have to do it properly and it does misty. i'll just say, don't be kicked out of the classes coast each must defeat down from the i'll send

them to you. so school getting kicked out means dian north and not teach. i showed them lunch. the tea cells learn to distinguish the bodies own cells from foreign invaders, full and kitchens. officer they've been trained. somebody used to kill us cells against pathogens, to destroy them. displaying is also a key part of the immune system. it's still of defense self. the relief whenever they needed and also felt as the blot was monthly. if they knew that you simply, you can think of the spleen is a big blood slate. as of the blood is filtered through it. and there are also macrophages in the margins, which we call scavenger cells in the i to t t saying they fish out old t cells, old blood cells and pathogens, and then dispose of them done. and so often the immune system has a huge off and all of health as that destroyed pathogens to keep us healthy, often without us even noticing. but sometimes you most definitely do

notice your body a school for it depends on your temperature rises, your immune system is working over time. if your body temperature associate degree celsius or higher, you officially have a c that it's on pleasant. no questions. but does it actually so the purpose of fever can really knock you out. it's a sign that the body is defending itself against an invader. it's turned out the temperature and is using it as a weapon. because many viruses and bacteria sensitive to heat, they multiply best temperatures around 37 degrees celsius. if the environment grows hossa and juice of fever, proceedings and some pathogen start to d, nature and clump. this prevents them from proliferation, and they dials a fever. it shows that the body is doing its job,

is to site have an important task and the defense against disease causing microwaves. these defense cells detect and fights invaders, such as viruses, will bacteria. to do so, they migrate to the site of infection and attacks of pathogens that 3, the can accelerate this process. this is because the body release is heat shield proteins, tab a boosting the lymphocytes, making them more efficient and better able to find viruses. you can't really say that a fever is always helpful or harmful, whether it's necessary to lower a fever also depends mainly on the patient. give us the student's name or can be dangerous for a certain age groups for very young patients. for example, infants under the age of one and also for elderly patients, people over 75. so age is

a factor and the other factor is existing conditions. if someone has a medical condition, then a high temperature has to be taken seriously. told most of the process is in our body what best of the temperature of 37 degrees. if the body is significantly hosta for an extended period of time, it can be dangerous. a fever or 40 degrees or more can lead to serious complications, even in otherwise healthy people. somebody gets in australia often cause severe dehydration and accelerated heart beat and dropping blood pressure. if this happens, then you definitely need to reduce the fever was. but there's no general rule about when to reduce a fever. what studies do show is that reducing one doesn't affect the duration of an illness. but so let's see here the fever is basically the body's sounding and alarm and saying, i have a problem, leave me alone. i have to sorted out and tackle the root of the problem. and the

body require strength to do that. if you reduce the fever and carry on and exert yourself as usual, you can end up making the illness worse than it needs to be at least a 5. what is important is to drink plenty of fluids to every degree higher than the normal body temperature. you should drink an extra liter. so if you have a temperature of $39.00 degrees celsius, you should drink about 5 inches of water per day in total. alternatively, medications can help reduce the temperature for several hours. you can also reduce body temperature with the cough compress, wrapping of cloth soaked in vinegar water around the cops for a few minutes. however, the effect will last for a whole day. it has to be repeated a few times. so this patient's temperature is back to normal. the west is a to be to work at its best. your immune system needs

a range of different my card, new chance love. it is rich and victim an 8 which is needed for the production of new cells. and the mucus membranes so inches the intestines and respiratory tract. oh, well um sweet potatoes contained pro vision in a which the body converts into victim in a, in the intestines. so an alternative for vegetarians, shellfish have a lot of think, essential for the production of various defend itself. studies show that a good supply of st protects children in particular from severe diarrhea like gains such as beans, chick peas and lentils also keep the body well supplied with think it's more easily observed when they're soaked or for mental but some foods can make the immune system over react and that can be life threatening. it looks so harmless,

but for about one percent of the population coming into even the slightest contact with the fragment of t not can be fatal. as i know that she is, i always say that a severe reaction to a pain us is like an accident where the tanka fighting can with children be i always don't to close out pretty quickly. dish. uh huh. they get a tightness and that chest, that makes it hard to breed. it can happen in a matter of minutes. as luca knows all too well, he and his family had no idea. he had a peanut allergy, but then 3 years ago, his little sister accidentally knocked over a bowl of peanuts on new year's eve. then lucas started helping to pick him up time, barely 3 minutes later he came to me in the kitchen with his lips swimming up like crazy. and i knew something was wrong. i'm personally skills love this. it has been

a fun evening until that happens. but then it suddenly got very serious. this don't make no mistake. lucas body had reacted to proteins contained in the peanut. he was about to go into an f electric shock and had to be rushed to the hospital. a severe allergic reaction to peanuts happens when peanut particles enter the body, either because they're eaten inhaled where the even just come into contact with the skin. the fragments are misinterpreted as an enemy by special anti bodies. these then bind to the peanut allergens. as a result, the mass sales activate, indeed granulated releasing huge amounts of the neurotransmitter histamine. the histamine dilates the blood vessels, blood pressure drops, blood stops flowing at a brisk rate. vital oregon such as the heart, lungs and brain are no longer supplied with oxygen. there's a risk of cardiovascular failure. and since the new year's eve incident, luca always carries an emergency,

get complete with an adrenalin pen. if he accidentally comes into contact with peanuts, he could save his life. the volume of adrenalin dilates the airways, which means that the patient can breathe again, and it constricts the dilated blood vessels. this raises blood pressure and boost circulation. lucas peanut allergy was a blow for him and his family, the fear that he would suffer another severe reaction was ever present. even tiny choices of peanuts compose a risk to allergy sufferers. but now lucca no longer has to worry. he's one of 30 children who took part in trials of a new oral immune therapeutics, the desensitize them to feel that allergens this involved eating a sort of flower containing peanut proteins every day. over a period of 6 months the dosage was slowly increased from $1.00 to $300.00

milligrams. the equivalent of a single peanut screen. i'm sure that you've clearly started quite well. i didn't have too much trouble. it didn't really taste like not enough, but then when it got to about 80 milligrams, it got worse. so can we ask, please mean he comes with some friends in business space that i had stomach pains and some other problems i don't understand and i was close to dropping out. but in the end, i decided to continue the therapy. so i don't have to worry about peanut trace is all the time of the time. he can now tolerate around $300.00 milligrams of the peanut flower, that's a whole p not to maintain the effect. so he has to regularly consume this dose is now lucca can even enjoy his favorite chocolate biscuits. again, without having to worry. he'd avoided them for 3 years because they might contain traces of peanuts. sometimes the immune system attacks the body's own

healthy tissue. this is called an auto immune disease, lupus, for example, it can lead to changes in the skin and information in the joints and organs pop stuff, selena gomez has lupus needed a kidney transplant. soon as seo has scars on his face as a result of the condition, treating it can be very challenging to tell which he is visiting this clinic in southern germany for a follow up examination. she has to have a complete checkup every 4 months. back in 2016 when she was 16 to tell contract that the severe auto immune disease systemic lupus arithmetic uses or s l e, and athletic teenager. at 1st, she mistook the symptoms for sore muscles to collect the joint pain didn't get any better, it got worse. and then in december i developed extreme fatigue. i got more and more tired. with lupus be immune system begins finding the body's own cells and attacks

internal organs. none of the attempts to treat to tell this condition were successful. in early 2021. all the treatment options had been exhausted. have you at that point i just had to cry. the disease wasn't getting any better. it was getting less. all i could do was lie down at home. i was in pain, i had breathing difficulties. hot palpitations. i wondered if i was going to die because that just wasn't to kill, couldn't have big. the doctors from the team, atalla, g and immunology departments at the university hospital long and for already researching a treatment for lupus patients employing t cells from the patient that are genetically engineered in the lab. at that point, the cell therapy had only been used in cancer treatment. it was offered to, to tell, as a last resort, was to get him to and he had to have to admit, quite honestly, i was very worried that it might not work at all because.
