Kuyini leukocyte? abavikeli Small umzimba

Lapho siya kudokotela, nginikeza phezu cwaningo, uyoba usuzwile leukocyte. Abantu abaningi bangaba nekuvisisa olukha phezulu kakhulu kubo, ngokuvamile kungagcini ngokwazi ukuthi eziqukethwe igazi, futhi nenombolo yabo luyanda futhi kwehle. Kuyacaca ukuthi wonke umuntu ufuna ukuba ube yakhe noma konke kuye kwaba okuvamile, kodwa kulokhu - kuyinsakavukela? Futhi ngokuvamile, uyini amangqamuzana amhlophe egazi?

Ake siphenye. Igazi lomuntu yakhiwa plasma bese ezikuyo ekumisweni kulencane izakhi eyakheke - egazi amhlophe, abomvu egazi nama-platelet. Leucocytes - okuthiwa kungekho nto enemibala emihle noma amhlophe egazi, okuyinto enze umsebenzi obalulekile wokuvikela umzimba womuntu kusuka zonke amagciwane nezinye izindikimba angaphandle, izindlela ezahlukene engena phakathi le wegazi nezicubu. Amabhiliyoni abavikeli amancane lijikeleze umzimba, sengathi ukugwema patrol bakhe, ukuba okulungele nganoma yisiphi isikhathi ukuze bacabangisise wodweshu.

Ukuze ukucabanga kangcono ukuthi amangqamuzana amhlophe egazi nokuthi asebenza kanjani, ungakwazi ukufinyelela kwesakho isifaniso nge ekulweni. Amangqamuzana amhlophe egazi - uhlobo onogada basemngceleni noma abezempi, okuyinto ukubona kwema- endaweni evikelwe izici ezinenzondo uzithatha empini ngaphandle kokulibala. Uma "mcekeli phansi" osayizi ezincane, amangqamuzana amhlophe egazi ithumba ibusa obala ukugaya intracellular. Uma usayizi nomzimba angaphandle iyindlela enhle welungelo kuthiwa ukugqugquzela esiphuthumayo esizeni izilonda oluhlehlela amabutho amangqamuzana amhlophe egazi, ngokuvumelana nemithetho yesayensi lempi angene naye indandatho futhi ababhubhise. Inqubo Ukugaya izakhi angaphandle libizwa phagocytosis. Kodwa akubona bonke ngakho elula - eqinisweni ukulwa esibulalayo, ngoba obulala amhlophe egazi amaseli ngokwabo. Empini igcwele "imizimba" izitha sibulawe futhi zizivikele ngokwabo, aphume lapho slurry viscous - ubomvu. Ngemva kwalokho, ama-leukocyte ngokwabo futhi ubeka izinto ngononina esizeni "sibhicongo".

Manje njengoba uthola umbono walokho LEUKOCYTE, bazibheke - kungakanani badinga umzimba sikwazi ukumelana nanoma imaphi kuhlasela zangaphandle ngokuphepha. kakhulu! Ngokuvamile inani lamaseli ilitha igazi ngayinye uyahluka 4-9 bhiliyoni. Yabo iba ezinkudlwana uma eziphuthumayo, lapho umzimba ukulwa nezifo, izifo ubovu, ukusha, noma ngenxa ukopha ezinzima. inqubo enjalo, lapho inani amangqamuzana amhlophe igazi kwanda kakhulu, okuthiwa leukocytosis. Ubhekisela udokotela, funda imiphumela cwaningo, yokuthi umzimba elwa sifo. Kodwa uma izivikelo kakade isafa, izivikeli mzimba ayikwazi ukunqoba lezi zinselele kusuka ngaphandle, leukopenia iqala - inqubo reverse, lapho inani abavikeli abasha incipha. Lo mphumela yokuhlaziya kuyisixwayiso: isiguli ngisesimweni esibucayi, ikhambi is hhayi, isibikezelo okungekuhle.

Ngakho siyazi ukuthi amangqamuzana amhlophe igazi Indlela Ezisithinta inani isimo lesiguli. Kodwa basuka kuphi, yini "mboni" emzimbeni wethu wenza "inkontileka ukuzivikela"? Umphakeli eyinhloko obomvu umnkantsha, okuyinto has a stem cells ekhethekile - kuzo ukuthi amangqamuzana amhlophe egazi akhiwa. Wena uke wezwa izifo ezifana nomdlavuza wegazi. Lena inqubo sokugembula lapho ekunqandeni maseli bakamalalahlengezela afe. Kulokhu, amangqamuzana amhlophe egazi musa sivuthwe futhi, naphezu kweqiniso lokuthi kuzala inqwaba, zingabe zisakwazi yenze imisebenzi yayo ebalulekile. Ngakho-ke, ngo-wegazi namuhla ngokwethukela asesebenzisa nokusebenza ukufakelwa umnkantsha ukuze uqhube inqubo yokuthuthukisa amakhono ephezulu grade egazi amhlophe.

Nokho, kukhona amacala lapho umuntu zingaphazamisana ngokuphilisa leukocyte. Yiziphi lezi zimo? Ukufakelwa of donor izitho. Ngo-leukocyte uyeza ukungqubuzana "amaqembu alwayo" uhlelo ukuhlonza, futhi ngolaka ukuhlasela izitho ezivela ngaphandle, okungaholela ukwenqaba isitho Ukufakelwa.
