Ntchito yaikulu ya maselo oyera: kufotokoza mwachidule

maselo oyera ndinu mmodzi wa maselo zofunika kwambiri thupi lonse. chakuti iwo apatsidwa ndi zosiyanasiyana ntchito. Pankhaniyi pali ambiri a mitundu leukocytes. Aliyense ali ndi mbali yapadera. Pakali pano, amadziwika kuti onse maselo oyera anawagawa mitundu zotsatirazi: neutrophils, eosinophils, basophils, monocytes ndi T-lymphocytes. Ntchito ya leukocytes mu magazi ikhoza kusintha kutengera mtundu wawo.

Udindo wa neutrophils

maselo amenewa ndi ofunika kwa anthu. chakuti kupereka chitetezo chodalirika cha thupi ku mitundu yonse ya bakiteriya ndiponso matupi ena achilendo. Iwo achite izo pakali 2 njira. The oyamba ikuchitika ndi phagocytosis. Zimenezi zikutanthauza kuti mayamwidwe mabakiteriya yachilendo kapena mbali yake. The chachiwiri - kusankha wapadera wa bactericidal ndi zinthu bacteriostatic.

ntchito eosinophils

Maselo amenewa ndi ofunika kwambiri kwa kuyenda kwa bwino njira matupi awo sagwirizana ndi yotupa. Kukhazikitsa mtundu wa leukocyte ntchito zimathandiza thupi kulimbana ndi matenda osiyanasiyana mofulumira.

Eosinophils, ngakhale kufunika kwake kwa thupi, ndipo nthawi zina munthu ndi disservice. Tikuyankhula zokhudza chakuti pamene kwambiri kuchuluka kwa imabwera awo kuchuluka kwa osauka matenda awo sagwirizana.

Ntchito ya basophils

maselo amenewa ali ndi luso mokwanira otsika kuwononga matupi yachilendo. Nchito ya mtundu wa maselo oyera kwagona kuti ndi kugonjetsedwa kwa matenda thupi kuchepetsa mwayi wake kuti uzigawidwa. chinthu Izi zimatheka ndi kumasulidwa ndalama zambiri histamine, zomwe zimabweretsa kutupa zimakhala. Iwo choopsa kufala kwa mavairasi ndi mabakiteriya.

ntchito monocytes

Anthu ambiri amadabwa kuti kodi ntchito imagwiridwa ndi maselo oyera a magazi a mtundu uwu. chakuti ali ndi mavuto angapo, kukhazikitsa potsata mlingo wa chitetezo anthu kwa onse achilendo, makamaka mabakiteriya ndi tizilombo tina. Choyamba, iwo apanga luso phagocytosis. Kachiwiri, monocytes kubala zinthu zapadera zimene wakhama mu mapangidwe chitetezo, umene uli wofunika kwambiri kwa chitetezo chokwanira komanso.

Ntchito ya T-lymphocytes

Nchito monga mtundu wa leukocytes ndi kuteteza chamoyo kuchokera onse achilendo ndi njiru. Choyamba tikulankhula, mwachibadwa, za mabakiteriya ndi tizilombo tina. T-lymphocytes kupondereza iwo ndi phagocytosis, komanso Kugawilidwa kwanthaka zinthu zapadera zimene zingawononge iwo, kapena kuletsa / m'mbuyo kukula.

Tikumbukenso kuti ntchito ya mtundu wa maselo oyera sikuthetsa kumeneko. chakuti iwo akugwira nawo ntchito kuwonongedwa kwa maselo mutated. Ndiko kuti, T-lymphocytes ali nawo yimitsira njira khansa.

Udindo ndi ntchito ya leukocyte ndi (T-lymphocytes), kutsegula kwa m'badwo wa lymphocytes B, amene ali ndi udindo kwa yokonza chitetezo chokwanira humoral. Popanda maselo amenewa ndi za aliyense chitetezo chodalirika a chamoyo N'zosachita kufunsa.
