Eyona umsebenzi iiseli ezimhlophe zegazi: inkcazelo emfutshane

iiseli ezimhlophe zegazi ungomnye iiseli ibalulekileyo emzimbeni wonke. Inyaniso ukuba siphathiswe afunisele ngokubanzi lwemisebenzi. Kule meko kukho inani elikhulu lweendidi leukocytes. Ngamnye kubo idlala indima ekhethekileyo. Ukuza kuthi ga ngoku, kwakusazeka ukuba zonke iiseli ezimhlophe zegazi yahlulwe iintlobo zilandelayo: neutrophils, eosinophils, basophils, monocytes kunye T-lymphocyte. Imisebenzi ye leukocytes egazini azifani, ngokuxhomekeke kuhlobo lwabo.

Indima neutrophils

iiseli Ezo zibalulekile abantu. Inyaniso ukuba zinika ukhuselo oluthembekileyo komzimba kuzo zonke iintlobo iintsholongwane kunye namanye amaqumrhu amazwe. Benza loo nto-2 iindlela. Eyokuqala kubo ikhutshwa phandle phagocytosis. Le nkqubo kuthetha iintsholongwane i ukufakwa langaphandle okanye iinxalenye zayo. Okwesibini - ukhetho ekhethekileyo bactericidal zingangeni bacteriostatic.

imisebenzi eosinophils

zibaluleke kakhulu ukuhamba eyiyo iinkqubo komzimba kunye ukudumba Ezi seli. Ukuphunyezwa kwale hlobo lomsebenzi leukocyte ivumela umzimba ukumelana zizifo ezahlukahlukeneyo ngokukhawuleza.

Eosinophils, nangona nokubaluleka kwayo umzimba, yaye ngamanye amaxesha kufuneka ukuba umntu dlel. Sithetha ngayo yokuba xa imali ngokugqithiseleyo okuba yabo enkulu yokuba izifo komzimba.

Imisebenzi ye basophils

iiseli anjalo amandla ephantsi ngokwaneleyo ukutshabalalisa namaqumrhu angaphandle. Imisebenzi yale hlobo iiseli ezimhlophe zegazi amanga neqiniso ukuba ngokoyiswa yosulelo omzimba inciphise amathuba ayo ukuba asasazwe. Le into kuphunyezwa nokukhululwa oluninzi histamine, nto leyo ebangela ukuba iindumbisa emzimbeni. Ukuba ziphazamise ukwanda iintsholongwane neebhaktiriya.

imisebenzi monocytes

Abantu abaninzi bayazibuza ukuba umsebenzi wenziwa iiseli ezimhlophe yale hlobo. Isibakala sokuba babe eziliqela iingxaki, ukuphunyezwa elandelwayo exhomekeke kwinqanaba ukhuseleko lwabantu kuzo zonke iintlanga, ingakumbi kwiintsholongwane. Okokuqala, eziqulunqile ubuchule phagocytosis. Okwesibini, monocytes ukuvelisa izinto ezizodwa othatha inxaxheba ukuyilwa omzimba, nto leyo ebaluleke kakhulu ukuze nezifo.

Indima T-lymphocyte

Imisebenzi ezifana uhlobo leukocytes kukukhusela eziphilayo ezivela kuzo zonke iintlanga ezingalungile. thina Okokuqala bonke ukuthetha, ngokwendalo, malunga kwiintsholongwane. T-lymphocyte abayithintelayo kubo phagocytosis, kwakunye nokwabiwa kwezinto ezizodwa ukuze abatshabalalise, okanye ubuncinane yokuma / isantya ukukhula kwabo.

Kufuneka kuqatshelwe ukuba ayipheli eli umsebenzi uhlobo iiseli ezimhlophe zegazi apho. Inyaniso ukuba nabo inxaxheba intshabalalo iiseli mutated. Oko kukuthi, i-T-lymphocyte inxaxheba kwezithandani kweenkqubo zomhlaza.

Indima nomsebenzi leukocyte (T-lymphocyte), okanye ipoti ye kwisizukulwana lymphocyte B, athi abenoxanduva kugcinwe nezifo humoral. Ngaphandle kwezi seli malunga naluphi na ukhuselo oluthembekileyo ephilayo kuba akukho mbuzo.
