Leukocytes yog ib lub hlwb tseem ceeb tshaj plaws hauv tag nrho lub cev. Qhov tseeb yog tias lawv muaj ntau yam sib txawv. Nyob rau tib lub sijhawm, muaj ntau hom leukocytes. Txhua tus ntawm lawv plays nws tus kheej lub luag haujlwm tshwj xeeb. Txog niaj hnub no, nws paub tseeb tias tag nrho cov leukocytes tau muab faib ua ntau yam hauv qab no: neutrophils, eosinophils, basophils, monocytes thiab T-lymphocytes. Tib lub sijhawm, cov haujlwm ntawm leukocytes hauv cov ntshav txawv nyob ntawm lawv hom.
Lub luag haujlwm ntawm neutrophils
Cov hlwb no tseem ceeb heev rau tib neeg. Qhov tseeb yog tias lawv muab kev tiv thaiv txhim khu kev qha rau lub cev los ntawm txhua yam kab mob thiab lwm lub cev txawv teb chaws. Lawv ua qhov no nyob rau hauv ob txoj kev. Thawj ntawm cov no yog ua los ntawm phagocytosis. Cov txheej txheem no suav nrog kev nqus cov kab mob txawv teb chaws lossis lawv qhov chaw. Qhov thib ob yog tso tawm tshwj xeeb bactericidal thiab bacteriostatic tshuaj.
Eosinophil tasks
Cov hlwb no tseem ceeb heev rau kev ua kom raug ntawm kev ua xua thiab cov txheej txheem inflammatory. Kev siv lub zog ntawm hom leukocytes no tso cai rau lub cev sai sai nrog ntau yam kab mob.
Eosinophils, txawm tias tag nrho lawvqhov tseem ceeb rau lub cev, qee zaum lawv ua kev puas tsuaj rau tib neeg. Peb tab tom tham txog qhov tseeb tias nrog ntau dhau ntawm lawv, qhov tshwm sim ntawm kev tsim kab mob ua xua ntxiv.
Basophil muaj nuj nqi
Cov hlwb zoo li no muaj peev xwm ua kom puas lub cev txawv teb chaws. Lub luag haujlwm ntawm leukocytes ntawm hom no yog txwv tsis pub nws muaj peev xwm kis tau yog tias lub cev cuam tshuam los ntawm tus kab mob. Lub hom phiaj no yog ua tiav los ntawm kev tso tawm ntau ntawm histamine, uas ua rau cov nqaij o tuaj. Lawv ua rau nws nyuaj rau cov kab mob thiab kab mob sib kis.
Monocyte Tasks
Ntau tus xav paub seb hom leukocytes ua haujlwm li cas. Qhov tseeb yog tias lawv muaj ntau txoj haujlwm ib zaug, qhov kev siv uas txiav txim siab txog qib ntawm tib neeg kev tiv thaiv los ntawm txhua yam txawv txawv, tshwj xeeb tshaj yog cov kab mob thiab kab mob. Ua ntej, lawv tau tsim muaj peev xwm phagocytosis. Qhov thib ob, monocytes tsim cov tshuaj tshwj xeeb uas koom nrog hauv kev tsim cov tshuaj tiv thaiv kab mob, uas tseem ceeb heev rau kev tiv thaiv kab mob.
Role ntawm T-lymphocytes
Lub luag haujlwm ntawm hom leukocytes no kuj yog los tiv thaiv lub cev ntawm txhua yam txawv teb chaws thiab muaj kev phom sij. Ua ntej tshaj plaws, peb tab tom tham, ntawm chav kawm, txog kab mob thiab kab mob. T-lymphocytes txwv lawv los ntawm phagocytosis, nrog rau kev tso tawm cov khoom tshwj xeeb uas tuaj yeem rhuav tshem lawv lossis tsawg kawg nres / qeeb lawv txoj kev loj hlob.
Nws tsim nyog sau cia rau ntawdCov haujlwm ntawm hom leukocytes no tsis xaus rau ntawd. Qhov tseeb yog tias lawv kuj koom nrog kev puas tsuaj ntawm cov hlwb mutated ntawm lub cev nws tus kheej. Ntawd yog, T-lymphocytes koom nrog hauv kev tawm tsam ntawm cov txheej txheem oncological.
Lub luag haujlwm ntawm kev ua haujlwm ntawm leukocytes (T-lymphocytes) raws li kev ua kom tsim cov B-lymphocytes, uas yog lub luag haujlwm rau kev tswj hwm kev tiv thaiv kab mob, kuj zoo heev. Yog tsis muaj cov hlwb no, tsis muaj lus nug txog kev tiv thaiv lub cev.
