Yintoni leukocytes? abavikeli ezincinane eziphilayo

Xa sisiya kugqirha, enikezela ngokuhlahlela, uya mhlawumbi nikuvile leukocytes. Abantu abaninzi babe ukuqonda phezulu kakhulu kubo, ngokubanzi kuphela ukwazi ukuba ziqulethwe igazi, yaye inani labo uyandiswa nokwehla. Kucacile ukuba wonke umntu ufuna ukuba sakhe okanye yonke yakhe eqhelekileyo, kodwa kulo mzekelo - eqhelekileyo? Yaye jikelele, yintoni na iiseli ezimhlophe zegazi?

Makhe uphando. igazi lomntu ubunjwe plasma kunye equlethwe kulo ezingadibaniyo incinane izinto kwakhiwa - kwiiseli zegazi ezimhlophe, iiseli ezibomvu neeplatelets. Leucocytes - ebizwa ngokuba ezingenambala okanye iiseli zegazi ezimhlophe, nto leyo yenza umsebenzi ebalulekileyo ekukhuseleni umzimba womntu ukusuka zonke izinto ezincinci kunye namanye amaqumrhu amazwe, iindlela ezahlukileyo zingene egazini kunye inyama. Iibhiliyoni of abavikeli ncinane lijikeleze emzimbeni, ngokungathi ekuphepheni wokuhamba wakhe, ukuba ukulungele nanini na ukuze baphendule umhlaseli.

Ukuze sikuqonde kakuhle oko iiseli ezimhlophe zegazi kwaye zisebenza njani, unako ukuzoba isifaniso kunye umlo. iiseli ezimhlophe zegazi - uhlobo loonogada komda okanye athathwe, apho ubona kwii-kwindawo ekhuselweyo eziqalelo ngolunya kubathabathela emfazweni ngaphandle kokulibazisa. Ukuba i "saboteur" ubukhulu zincinci, iiseli ezimhlophe zegazi ithumba kubadle kwaye akukukhuseli ukugaywa intracellular. Ukuba ubungakanani umzimba amazwe olukhulu umdlali okhuselayo eye uvakaliswa ngokugaya engxamisekileyo nesiza izitshanguba nciphisa imikhosi iiseli ezimhlophe zegazi, ngokungqinelana nemigaqo yenzululwazi zomkhosi amamkelele kuloo umsesane nokutshabalalisa. Inkqubo ukwetyisa lweziqalelo amazwe kuthiwa phagocytosis. Kodwa asingabo bonke elula kunjalo - ke enyanisweni idabi ebulalayo, kuba ubulala iiseli zegazi ezimhlophe ngokwabo. Le ledabi igcwele "imizimba 'iintshaba kubulawa kunye ngabakhuseli ngokwabo, ngaphandle apho oluludaka viscous - ubomvu. Kamva, leukocytes ngokwabo izinto ukuze esizeni "nendyikitya".

Ke kaloku, ukuba umelwe kukuba ufifi lokuba yintoni leukocytes, cinga ngokwabo - kangakanani kufuneka umzimba ukumelana ngokukhuselekileyo nokuhlaselwa lwangaphandle. kakhulu! Ngokwesiqhelo inani leseli nganye igazi ilitha uyahluka 4-9 billion. Zabo iba ezinkulu kwiimeko ezingxamisekileyo, xa izifo kulwa umzimba, izifo ubovu, ukutsha, okanye ngenxa ukopha kakhulu. Loo inkqubo, xa inani iiseli ezimhlophe ukunyuka kakhulu, ebizwa leukocytosis. Walatha kugqirha, funda iziphumo wohlalutyo, into yokuba umzimba ekulweni esisifo. Kodwa ukuba zokuzikhusela sele kwi sekuqengqeleke, amajoni omzimba akakwazi ukumelana neengxaki ezivela ngaphandle, leukopenia uqala - inkqubo umva, apho inani abavikeli abatsha siyehla. Le ngenxa analysis sisilumkiso: isigulana ikwimeko esinzulu, unyango elingekhoyo, uqikelelo elingamncediyo.

Ngoko ke siyayazi ukuba iiseli zegazi ezimhlophe kunye nangendlela oku kunempembelelo ngayo isixa imeko yesigulane. Kodwa apho ivela, yintoni "mveliso" ngaphakathi emzimbeni wethu wenza i "isivumelwano ukuziphendulela '? Umthengisi engundoqo ebomvu lomongo wethambo, nto leyo iba iiseli ezikhethekileyo stem - kubo ukuba iiseli ezimhlophe zegazi kwakheka. Umelwe weva izifo ezifana wegazi. Le yinkqubo zophendlo lwezifo apho siyenza iiseli kufa zehle kakhulu. Kulo mzekelo, iiseli ezimhlophe zegazi musa angakhuli kwaye, nangona yokuba ngemithamo emikhulu, aze angakwazi ukwenza imisebenzi yayo ebalulekileyo. Ngoko ke, xa ileukemia namhlanje uya sokudala imisebenzi esinye lomongo wethambo ukuba aqalise inkqubo yokuphuhlisa iiseli ophezulu-grade igazi emhlophe.

Noko ke, kukho iimeko apho umntu zinokuphazamisana impiliso yi leukocytes. Yintoni na le meko? Abohlukeneyo izitho kubalizi. Xa leukocytes ezayo inkqubo yokuchonga "umhlobo okanye utshaba" impixano, yaye ngengcwangu inyama kwamanye amazwe, nto leyo inokukhokelela kokukhatywa nokufakelwa amalungu omzimba.
