Leukocyte igazi okuphezulu

Amangqamuzana amhlophe egazi - ayinayo umbala kwamangqamuzana egazi abomvu. Ziyakwazi uhlaba monocytes, ihlukene, kuye ukuma nucleus. Futhi ukuhlukanisa granulocytes - amangqamuzana amhlophe egazi sihlangane namatshana isici kule cytoplasm futhi agranulocytes - leukocyte ngaphandle kwalo. Ngo izifundo endaweni yokucwaninga, bona zipendwe ngemibala ehlukile, futhi ngenxa yalokho, amagama ahlukene nalabo imisebenzi ukuthi enze: eosinophil, basophil, neutrophil.

Amangqamuzana amhlophe egazi amahhala ukushiya ukusakaza igazi ngenkuthalo ukuhambisa ezikhaleni phakathi amaseli. umsebenzi wabo oyinhloko - ukuvikela. Uma umzimba is phansi sanoma yikuphi ukulimala kwe-ke futhi izinto angaphandle iwe futhi leukocyte, uma ku umyalo, zingene izindonga capillary (zndoteliya ngokusebenzisa amangqamuzana) futhi ngokushesha ukuthuthela umthombo ethintekile. Kukhona zizungezwe isici amazwe angaphandle, okuyinto kubonakala ethe njo ebusweni, bese udweba ke phakathi ne inhlabamkhosi. Inqubo bamba ngokushesha nokubhujiswa izinhlayiya angaphandle efile futhi siphile (mikroskopichskih isikhunta, amagciwane), okuyinto engena emzimbeni, ebizwa ngokuthi phagocytosis naweselula lithwalwe - fagotsitami.Esli kukhona isidingo isivikelo esinjalo, isiginali okuhambisanayo ihlinzekwa ezithweni hematopoietic, futhi basheshe baqale ukukhiqiza inani elikhulu amangqamuzana amhlophe egazi. Ukusabela kwenzeka phagocytosis. Ucingo okwethusayo ephendula nezinye abizwa ngokuthi ama-macrophage, okwakukhona kuze kube yileso sikhathi esimweni sokungenzi lutho. Baqala ukuthuthela endaweni ezilimele. Ama-macrophage, amangqamuzana amhlophe egazi nezinye egazi zinengxenye abatholako asebenzayo amagciwane athile kanye amagciwane. Ngaphezu kwalokho, ababhubhise labo amaseli umzimba okuyinto pootmerli ngenxa yokugula noma yokulimala, futhi ngaleyo ndlela nahlanza ke kusukela uwohloka, engakwazi izinhlayiya eziphilayo. Lokhu kuwachaza kahle okuqukethwe lelitfutfukile leukocyte egazini. umngcele isilinganiso sabo amabanga kusuka 4000 kuya 9000 ngo 1 l zabantu ezahlukene. Kuyadingeka ukwazi ukuze abone high blood leukocyte noma cha. Iyehla iyenyuka ngaphakathi amayunithi ayizinkulungwane eziyisihlanu kungenzeka ngisho kwelinye kanye nomuntu ofanayo, futhi kuncike isikhathi sosuku: ntambama inombolo yabo uvelichivaetsya.Vychislit ivumela izinga ifomula ekhethekile, ikhumbula lihlela isilinganiso phakathi kwama ezihlukahlukene leukocyte. Nokho, nawo ziyahlukahluka phansi noma okuphambene nalokho.

Amazinga aphakeme egazi amhlophe - 9,000 - ngokuthi leukocytosis, futhi ongaphakeme - ngaphansi kuka-4000 - leukopenia. Ukuguquguquka lemali futhi isilinganiso sabo amafomu ngokuvamile iyisiginali izinqubo sokugembula emzimbeni. Nokho, akunakwenzeka ukuba acabangele kuphela isibonakaliso futhi musa acabangele isimo jikelele umuntu. Bobabili izinqubo kungabonakala nasemkhakheni umzimba ephelele. Ngokwesibonelo, ngemva okugeza, kubhavu ashisayo, ukuzivocavoca, okhandlayo emva evamile leukopenia yesikhashana kwenzeka. Wokuqukethwe iDemo okusezingeni eliphezulu amangqamuzana amhlophe egazi kwenzeka emva kokudla, ngemva okhandlayo-non-ehlelekile, lapho supercooling. Inombolo yabo kungase kwandise ngesikhathi sokukhulelwa, nezinye izinguquko zomzimba womuntu. Ngokwesibonelo, e necrosis kwezicubu ngemva kokushaywa yinhliziyo, ukuhlukumezeka, ukulahlekelwa igazi, ngazo zonke izinhlobo zezinto komzimba lenyuka igazi ezimhlophe cell count - into njalo. Ngakho umzimba liveza impendulo zokuzivikela.

Cacisa isizathu ekushintsheni rates abo phezulu kuzosiza abavamile kwegazi. Ngokuvamile isifundo aphansi lohleliwe lembula abantu abebecabanga ukuthi bangabalandeli enempilo, lesi sifo igazi ngendlela efanele usaqala, okuvumela ukwelashwa futhi sisiqhube ngendlela ephumelelayo.
