Qhov sib txawv tseem ceeb ntawm cov qe ntshav liab thiab cov qe ntshav dawb yog cov haujlwm uas nws ua. Cov qe ntshav liab thauj oxygen los ntawm lub ntsws mus rau cov hlwb thiab cov ntaub so ntswg ntawm lub cev thiab thauj carbon dioxide los ntawm cov ntaub so ntswg mus rau lub ntsws. Cov qe ntshav dawb yog ib feem ntawm lub cev tiv thaiv kab mob uas pab tiv thaiv cov kab mob uas nkag mus rau hauv lub cev.
Ntshav yog cov ntaub so ntswg sib txuas. Nws muaj ob yam khoom: plasma thiab cov qe ntshav. Cov ntshav plasma yog cov kua nplaum alkaline uas suav txog 55% ntawm tag nrho cov ntshav ntim. Cov qe ntshav nyob ntawm qhov seem ntawm 45% ntawm cov ntshav ntim. Muaj ob hom ntshav loj uas yog cov qe ntshav liab thiab cov qe ntshav dawb.
Ntshav liab yog dab tsi?
cov qe ntshav liab (RBC) lossis erythrocytes yog hom cell ntau tshaj plaws hauv cov ntshav (4.5-5.5 lab). Lawv muaj cov duab biconcave, thiab lawv txoj kab uas hla yog 6 µm. Lawv tsis muaj nucleus raws li kev hloov kho kom ua tiav lawv txoj haujlwm zoo. Lub neej ntawm RBC yog li 120 hnub; nws raug rhuav tshem hauv tus po/siab.
Daim duab 01: ntshav liab
Kev tsim cov RBC tshwm sim hauv cov pob txha pob txha loj. Lub xub ntiag ntawm cov xim liab hemoglobin pigment uas sib txuas nrog cov pa oxygen yog qhov tseem ceeb ntawm erythrocytes. Cov enzyme carbonic anhydrase pab thauj cov pa roj carbon dioxide ntawm cov hlwb mus rau lub ntsws.
Ntshav Qab Zib yog dab tsi?
Leucocytes lossis cov qe ntshav dawb (WBC) yog ib hom qe ntshav loj. Lawv yog spherical nyob rau hauv cov duab thiab tsis muaj xim piv rau cov qe ntshav liab. Tus naj npawb ntawm WBCs hauv cov ntshav muaj ntau ntawm 7, 000-10, 000 / mm 3 Muaj tsib hom WBCs uas tuaj yeem paub qhov txawv ntawm lawv cov cim staining, qhov loj thiab cov duab ntawm lawv cov nuclei.
Daim duab 02: cov qe ntshav dawb
Raws li tus cwj pwm staining, muaj ob hom: granulocytes thiab agranulocytes. Granulocytes muaj lobed nucleus thiab granulated cytoplasm. Lawv txhua tus muaj peev xwm ntawm amoeboid txav thiab tau muab faib ntxiv rau hauv neutrophils, eosinophils, thiab basophils. Neutrophils thiab eosinophils muaj peev xwm ntawm phagocytising txawv teb chaws invasive hlwb, thiab cellular secretion ntawm hais. Basophile granules muaj cov tshuaj histamines thiab heparin, uas pab ua rau muaj kev mob tshwm sim. Agranulocytes muaj cov cytoplasm uas tsis yog granular thiab ib qho oval los yog taum-puab nucleus. Muaj ob hom agranulocytes tseem ceeb: monocytes thiab lymphocytes. Cov no pab lub cev tiv thaiv kab mob thiab kab mob sab nraud los ntawm phagocytosis thiab ua cov tshuaj tiv thaiv kab mob, feem.
Dab tsi zoo sib xws ntawm Cov Ntshav Liab thiab Ntshav Dawb?
- qe ntshav liab thiab cov qe ntshav dawb yog cov khoom tseem ceeb ntawm cov ntshav.
- Lawv yog cov hlwb tseem ceeb heev rau tsiaj.
- Ob leeg pib rau tib lub cell.
- ob leeg yog tsim nyob rau hauv cov pob txha pob txha.
Dab tsi yog qhov txawv ntawm Cov Ntshav Liab thiab Ntshav Dawb?
qe ntshav liab, (erythrocyte) yog ib lub cell zoo li biconcave pom nyob rau hauv cov ntshav uas thauj gases ntawm thiab mus rau lub ntsws. Nyob rau hauv sib piv, cov qe ntshav dawb yog ib tug spherical zoo li lub cell uas ua hauj lwm raws li ib tug tiv thaiv cell. Raws li lawv lub npe qhia, yav dhau los yog xim liab, tab sis tom kawg yog xim tsis muaj xim. Ntxiv mus, cov qe ntshav liab suav txog 40-45% ntawm tag nrho cov ntshav. Tsuas muaj ib hom qe ntshav liab xwb. Tsawg suav ntawm nws ua rau muaj ntshav liab. Txawm li cas los xij, cov qe ntshav dawb suav txog 1% ntawm tag nrho cov ntshav. Nws muaj tsib hom: neutrophils, basophils, eosinophils, lymphocytes, thiab monocytes. Tsawg suav ntawm cov hlwb no tuaj yeem ua rau leucopenia.
Ntxiv rau, cov qe ntshav liab raug tsim los ntawm cov txheej txheem hu ua erythropoiesis thaum cov qe ntshav dawb raug tsim los ntawm cov txheej txheem hu ua leucopoiesis. Lub neej yav tas los muaj 120 hnub thaum lub neej yav tas los muaj 5 txog 21 hnub.
Summary – Ntshav Liab vs Ntshav Dawb
qe ntshav liab thiab ntshav dawb yog ob yam ntawm cov qe ntshav. Cov qe ntshav liab yog hom cell uas muaj ntau tshaj plaws uas thauj cov pa oxygen thiab carbon dioxide los ntawm thiab mus rau lub ntsws. Cov qe ntshav dawb ua haujlwm hauv kev tiv thaiv kab mob. Qhov no yog qhov txawv ntawm cov qe ntshav liab thiab cov qe ntshav dawb.
