<prompt> Tsamaiso ea mele ea ho itšireletsa mafung e loantša tšoaetso joang?nan  <response>: Instruction in English: How does the human immune system fight infection? . Response in English: The human immune system is an incredible defense mechanism that helps protect the body against harmful invaders like bacteria, viruses, fungi, and parasites, which can all cause infection. When an infection occurs, several key mechanisms are activated to fight it:1. Physical barriers: The skin acts as a physical barrier to prevent pathogens from entering the body. The mucous membranes of the respiratory, digestive, and urinary tracts also trap and expel pathogens.2. Recognition and response: When a pathogen enters the body, the immune system recognizes it as foreign and initiates a response. White blood cells such as macrophages, neutrophils, and dendritic cells engulf and destroy the invader.3. Inflammation: During an infection, the affected area may become red, swollen, and warm as the body increases blood flow to deliver more immune cells to fight the infection. This is known as inflammation.4. Specific immune response: The immune system also has a specific response to certain pathogens. Lymphocytes B cells and T cells recognize and target specific markers antigens on the pathogen. B cells produce antibodies that neutralize the pathogen, while T cells directly attack and destroy infected cells.5. Memory: After successfully fighting an infection, the immune system retains a memory of the pathogen. This means that if the same pathogen enters the body again, the immune system can quickly produce the specific antibodies needed to destroy it, preventing infection.Through these mechanisms, the immune system effectively fights infection and helps keep the body healthy. . Response in Sesotho: Sesole sa mele oa motho ke mokhoa o makatsang oa tsireletso o thusang ho sireletsa mele khahlanong le bahlaseli ba kotsi joalo ka libaktheria, livaerase, li-fungus le likokoana-hloko, tseo kaofela li ka bakang tšoaetso. Ha tšoaetso e hlaha, ho sebelisoa mekhoa e mengata ea bohlokoa ho e loantša: 1. Litšitiso tsa mele: Letlalo le sebetsa e le thibelo ea mele ho thibela likokoana-hloko ho kena meleng. Lera la mucous la matšoafo, tšilo ea lijo, le moroto le tsona li tšoasa le ho leleka likokoana-hloko. 2. Tlhokomeliso le karabelo: Ha kokoana-hloko e kena meleng, sesole sa mele se e hlokomela e le sesele me se qala karabelo. Lisele tse tšoeu tsa mali tse kang macrophages, neutrophils, le lisele tsa dendritic lia koaela le ho senya mohlaseli. 3. Ho ruruha: Nakong ea tšoaetso, sebaka se amehileng se ka na sa e-ba khubelu, sa ruruha le ho futhumala ha mele o eketsa phallo ea mali ho fana ka lisele tse ngata tsa mele tsa ho itšireletsa mafung ho loantša tšoaetso. Sena se tsejoa e le ho ruruha. 4. Karabelo e khethehileng ea mele ea ho itšireletsa mafung: Tsamaiso ea mele ea ho itšireletsa mafung e boetse e na le karabelo e khethehileng ho likokoana-hloko tse itseng. Li-lymphocyte lisele tsa B le lisele tsa T li lemoha le ho lebisa matšoao a itseng li-antigen ho pathogen. Lisele tsa B li hlahisa lithibela-mafu tse fokotsang kokoana-hloko, ha T lisele li hlasela ka ho toba le ho senya lisele tse tšoaelitsoeng. 5. Khopolo: Ka mora ho loantša tšoaetso ka katleho, sesole sa mele se boloka mohopolo oa pathogen. Sena se bolela hore haeba kokoana-hloko e tšoanang e kena meleng hape, sesole sa mele se ka hlahisa li-antibodies tse khethehileng tse hlokahalang ho e senya, ho thibela tšoaetso. Ka mekhoa ena, sesole sa mele se loantša tšoaetso ka katleho me se thusa ho boloka mele o phetse hantle.
