Ntshav - ib lom kua, lossi circulating nyob rau hauv cov ntshav system uas muaj as-ham thiab roj cua. Tsaug rau nws, muaj yog ib lub cev metabolism, ntaub so ntswg thiab kabmob tau txhua yam tsim nyog rau lawv lub neej thiab muab cov khoom ntawm metabolism. Nws muaj hlwb hu ua tsim ntsiab thiab ntshav. Ntshav ua li ib tug me ntsis ntau tshaj li 40% ntawm cov ntshav ntim, tus so yog lees paub rau cov kua ib feem ntawm cov ntshav - ntshav. Cov ntshav nyob rau hauv lub cev ua ntau yam tseem ceeb functions - noj haus, ua pa, kev tiv thaiv, thaum tshav kub kub hloov lwm lub tsev.

Tag nrho cov ntshav raug muab faib ua peb pawg loj ntawm hlwb - ntshav liab, qe ntshav dawb thiab platelets. Lub ntsiab loj ntawm hlwb comprise cov ntshav liab, tej zaum hu ua cov ntshav liab. Namely ntshav liab muab cov ntshav liab. Lub ntsiab muaj nuj nqi ntawm lub erythrocyte - mus nqa tawm cov roj pauv, i.e. thauj oxygen mus rau lub cev lub hlwb thiab mus sau los ntawm lawv cov pa roj carbon dioxide. Mus nqa tawm nkev pauv cov ntshav liab muaj ib tug tshwj xeeb protein hemoglobin. Tus duab ntawm cov ntshav liab zoo li concave rau ob tog ntawm lub disc. Vim li ib tug daim ntawv lawv yuav tau yooj yim mus rau mus rau hauv qhov tsawg tshaj plaws cov hlab ntsha. Nyob rau hauv tas li ntawd, lub concave rau ob sab ua rau nws ua tau rau kom tus nplaim ntshav liab uas yog tsim nyog rau ib tug zoo dua cov pa thauj. Ntshav liab muaj tsis muaj nuclei. Cov lifespan ntawm cov hlwb yog los ntawm 90 mus rau 120 hnub, nyob rau tus nqi ntawm ib tug liter ntawm cov ntshav ntawm cov txiv neej, nyob rau nruab nrab muaj 5x10 12 degrees, thiab rau cov poj niam - nyob rau hauv 12 degree 4,5h10 erythrocytes.

Tus tom ntej hom ntshav - ntshav dawb, uas yog, cov qe ntshav dawb. Cov txoj kev hais ua ib qho tseem ceeb luag hauj lwm nyob rau hauv kev tiv thaiv lub cev tiv thaiv pathogenic cov kab mob, kab mob, thiab ntau yam txawv teb chaws tshuaj. Lawv ntxuav lub site ntawm kab mob tom qab kev puas tsuaj ntawm cov kab mob, ua tshuaj, uas ua si ib qho tseem ceeb luag hauj lwm nyob rau hauv lub tsim ntawm kev tiv thaiv. Dawb ntshav nyob rau hauv cov pob txha hlwb, tus po, cov qog ntshav hauv. Qhov tsis muaj kob hlwb nrog zoo-tsim tsuab. Cov ntsiab lus ntawm cov ntshav dawb nyob rau hauv tib neeg cov ntshav - 4-10h10 nyob rau hauv lub cuaj degree ib liter ntawm cov ntshav.

Nyob ntawm seb cov nyob rau ntawm grain nyob rau hauv lub cytoplasm ntawm lub leukocytes raug muab faib ua granulocytes thiab agranulocytes. Los ntawm granulocytes yog eosinophils, basophils thiab qe, mus agranulocytes - lymphocytes thiab monocytes. Txhua yam ntawm cov ntaub ntawv ntawm cov ntshav dawb muaj nws tus kheej specialization, yog lub luag hauj lwm rau kev ua tau zoo ntau hom kev khiav dej num.

Ntshav hu ua platelets, nyob rau hauv qhov tseeb, yog tawg tsam ntawm loj hlwb - megakaryocytes. Platelets kuj hu ua platelets. Zoo li leukocytes, lawv yog tsis muaj kob, tsis muaj nuclei, yog lus rau hauv cov duab. Platelets yog tsis tshua muaj neeg nrov heev nthe, sai pov tseg nyob rau hauv tshiab npaj. Platelets ua si ib qho tseem ceeb luag hauj lwm nyob rau hauv lub folding txheej txheem, tus tsim ntawm cov ntshav txhaws thiab tsis txhob los ntshav. ntshav platelet suav yog hom twg los ntawm 200 mus rau 400h10 9 degrees ib liter ntawm cov ntshav.

Ntshav yog tsim nyob rau hauv lub hematopoietic kabmob, uas yog cov hlwb pob txha, cov qog ntshav hauv, tus po. Nyob rau hauv lub cev, muaj ib tug inextricable txuas tsim ntsiab nrog rau lub cev nyob rau hauv uas lawv ua thiab rhuav tshem thiab lub tsev cov kev cai ntawm txoj kev no.

Cov ntsiab lus ntawm ntau hom ntawm daim ntawv ntsiab - ib tug kuj tas li tus nqi. Txawv txav yuav ua tau ib qho tseem ceeb cov tsos mob ntawm ntau yam kab mob. Number ntau hom ntawm cov ntshav no qhia cov ncauj lus kom ntxaws general tsom xam ntawm cov ntshav leukocyte mis. Qhov no tsom xam muaj xws li tus nqi ntawm cov qe ntshav liab, xim index, erythrocyte sedimentation tus nqi, ntshav hlwb. tsom xam cov lus qhia tau hais tias tag nrho cov indicators yog dab tsi, uas tau yuav muab piv.
