Yuav ua li cas yog leukocytes? Me defenders ntawm tus kab mob

Thaum peb mus rau tus kws kho mob, handing tshaj ntsuam, koj yuav zaum tau hnov ntawm leukocytes. Feem ntau cov neeg muaj ib tug heev ces dag to taub lawv, yog feem ntau yog tas rau cov uas paub hais tias lawv yog muaj nyob rau hauv cov ntshav, thiab lawv muaj pes tsawg yog nce thiab poob. Nws yog tseeb hais tias txhua leej txhua tus xav kom muaj nyob rau hauv nws los yog nws txhua yam yog dab tsi, tab sis nyob rau hauv cov ntaub ntawv no - lub cai? Thiab nyob rau hauv Feem ntau, dab tsi yog qhov ntshav dawb?

Wb soj ntsuam. Tib neeg cov ntshav yog muaj li ntawm ntshav thiab muaj nyob rau ntawd nyob rau hauv ncua kev kawm ntawv tsawg tshaj plaws tsim ntsiab - ntshav dawb, ntshav liab thiab qe ua ntshav khov. Leucocytes - ib tug thiaj li hu ua film los yog ntshav dawb, uas ua ib qho tseem ceeb ua hauj lwm ntawm kev tiv thaiv tib neeg lub cev los ntawm txhua micro-kab thiab lwm yam txawv teb chaws lub cev, sib txawv paths tob tob mus rau hauv cov ntshav thiab cov ntaub so ntswg. Qas txhiab qas vam me me defenders circulate los ntawm lub cev, raws li yog hais tsis txhob nws saib xyuas, ua npaj tos txhua lub caij tau tuaj mus rau grips nrog lub tus tsim txom.

Nyob rau hauv thiaj li yuav zoo dua xav txog tej yam dab tsi rau hauv lub qe ntshav dawb thiab yuav ua li cas lawv ua hauj lwm, koj muaj peev xwm kos ib analogy nrog lub sib ntaus sib tua. Dawb ntshav - ib hom ntawm ciam teb tiv thaiv los militia, uas ntes cov allergic ntawm tus tiv thaiv cheeb tsam ntawm lub hostile ntsiab thiab coj lawv mus rau hauv sib ntaus sib tua tsis muaj kev ncua. Yog hais tias lub "saboteur" ntau thiab tsawg pab yog me me, cov ntshav dawb cell captures nws kov thiab exposes intracellular digestion. Yog hais tias qhov luaj li cas ntawm lub teb chaws lub cev yog zoo rau ib tug neeg yog hais tias tus ceev mobilization mus rau lub site ntawm txhab ntsws rog cov ntshav dawb, raws li cov kev cai ntawm cov tub rog science coj nws mus rau hauv lub nplhaib thiab rhuav tshem. Tus txheej txheem ntawm kev zom ntawm txawv teb chaws hais no hu ua phagocytosis. Tab sis tsis yog txhua txhua thiaj li yooj yim - nws yog nyob rau hauv qhov tseeb ib cov sib ntaus sib tua, vim hais tias nws tua cov qe ntshav dawb rau lawv tus kheej. Lub battlefield yog studded "lub cev" cov yeeb ncuab tua thiab protectors lawv tus kheej, tawm ntawm uas ib tug khov slurry - kua paug. Tom qab, leukocytes lawv tus kheej thiab muab tso rau tej yam uas nyob rau hauv kev txiav txim rau ntawm qhov chaw ntawm "carnage".

Tam sim no uas koj twb tau txais ib lub tswv yim dab tsi leukocytes, xav txog lawv tus kheej - ntau npaum li cas lawv yuav tsum tau qhov lub cev mus yam xyuam xim mas tej lwm nres. Heev npaum li cas! Feem ntau cov xov tooj ntawm hlwb ib liter ntshav mas nws txawv ntawm 4-9 billion. Lawv ua loj nyob rau hauv cov ntaub ntawv ntawm thaum muaj xwm ceev, thaum lub cev tua kab mob, purulent kab mob, kub nyhiab, los yog vim yam mob loj heev los ntshav. Xws li ib tug txheej txheem, thaum lub xov tooj ntawm cov ntshav dawb nce ho, hu ua leukocytosis. Nws cov ntsiab lus rau tus kws kho mob, nyeem cov kev tshwm sim ntawm analyses, qhov tseeb hais tias lub cev yog sib ntaus sib tua tus kab mob. Tiam sis yog tias defenses twb nyob rau lub wane, lub cev tsis muaj peev xwm mus puag nrog cov kev sib tw los ntawm sab nraum, leukopenia pib - qhov rov qab tus txheej txheem, nyob rau hauv uas lub xov tooj ntawm cov tub ntxhais defenders yog shrinking. Qhov no tshwm sim ntawm tus tsom xam yog ib tug ceeb toom: tus neeg mob nyob rau hauv loj mob, ib tug kho tsis yog, tus forecast yog unfavorable.

Yog li ntawd peb paub dab tsi lub qe ntshav dawb thiab yuav ua li cas lawv muaj kev cuam tshuam cov nyiaj ntawm tus neeg mob tus mob. Tab sis qhov uas lawv tuaj ntawm, cas "Hoobkas" hauv peb lub cev ua ib tug "tiv thaiv daim ntawv cog lus"? Lub ntsiab tsum yog cov liab pob txha, uas muaj ib tug tshwj xeeb qia hlwb - los ntawm lawv hais tias lub qe ntshav dawb tsim. Koj twb tau hnov txog tej kab mob raws li leukemia. Qhov no yog ib pathological kev nyob rau hauv uas qia hlwb yog massively tuag. Nyob rau hauv cov ntaub ntawv no, cov qe ntshav dawb tsis paub tab thiab, txawm lub fact tias lawv tsim loj qhov ntau, lawv yuav tsis ua nws tseem ceeb heev functions. Yog li ntawd, nyob rau hauv leukemia hnub no yog nce resorting rau khiav hauj lwm ntawm ib tug hloov hlwb pob txha los rov pib dua tus txheej txheem ntawm kev tsim high-qib cov ntshav dawb.

Txawm li cas los, tseem muaj mob qhov twg ib tug neeg tej zaum yuav cuam tshuam nrog rau cov tom qab yog leukocytes. Yuav ua li cas yog no? Hloov ntawm pub kabmob. Nyob rau hauv leukocytes los teeb meem "phooj ywg los yog foe" ID system, thiab lawv fiercely tua txawv teb chaws cov ntaub so ntswg, uas yuav ua tau kom tau cov rejection uas hloov khoom nruab nrog hloov.
