Qhov sib txawv tseem ceeb ntawm granular thiab agranular leukocytes yog tias granular leukocytes muaj granules hauv lawv cov cytoplasm, tab sis agranular leukocytes tsis muaj granules hauv cytoplasm.
Leukocytes lossis cov qe ntshav dawb 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 lawv cov nuclei. Raws li tus cwj pwm staining, muaj ob hom granulocytes thiab agranulocytes.
Granular Leukocytes yog dab tsi?
Granular leukocytes yog cov leukocytes uas muaj granules hauv lawv cov cytoplasm. Granulocytes muaj lobed nucleus. Lawv txhua tus muaj peev xwm ntawm amoeboid txav thiab tau muab faib ntxiv rau hauv neutrophils, eosinophils thiab basophils.
Neutrophils yog cov qe ntshav dawb ntau tshaj plaws nyob rau hauv peb cov hlab ntsha suav txog 55-70% ntawm tag nrho cov qe ntshav dawb. Cov hlwb no tseem ceeb heev vim tias lawv tuaj yeem txav mus los ntawm cov phab ntsa ntawm cov hlab ntsha thiab mus rau hauv cov ntaub so ntswg ntawm peb lub cev thiab tam sim ntawd tawm tsam tag nrho cov antigens. Qhov tseeb, neutrophils yog ib qho ntawm thawj hom cell uas khiav tam sim ntawd mus rau qhov chaw kis kab mob. Cov hlwb no tsim ib feem tseem ceeb ntawm lub cev tiv thaiv kab mob.
Daim duab 01: Granulocytes thiab Agranulocytes
Basophil yog lwm hom granular leukocyte. Basophils muaj granules ntawm lawv qhov chaw. Cov granules no muaj cov enzymes hu ua histamine thiab heparin. Cov enzymes no tseem ceeb hauv kev mob, ua xua thiab mob hawb pob. Lawv feem ntau pom nyob rau ntawm daim tawv nqaij thiab cov ntaub so ntswg mucosa, uas yog cov ntaub so ntswg ntawm qhov qhib hauv lub cev. Basophils suav txog 1% ntawm tag nrho cov qe ntshav dawb hauv lub cev.
Eosinophils yog peb hom granular leukocytes uas pab tiv thaiv kab mob. Tus naj npawb ntawm eosinophils hauv peb cov ntshav nce ntxiv thaum muaj kab mob parasitic, ua xua lossis mob qog noj ntshav.
Agranular leukocytes yog dab tsi?
Agranular leukocytes yog cov leukocytes uas muaj cov cytoplasm uas tsis yog granular thiab ib lub oval lossis lub noob taum zoo li cov noob. Muaj ntau hom agranulocytes ua monocytes thiab lymphocytes. Agranulocytes pab peb lub cev tiv thaiv kab mob thiab kab mob sab nraud los ntawm phagocytosis thiab ua cov tshuaj tiv thaiv.
Monocytes yog hom qe ntshav dawb loj tshaj plaws uas suav txog 2-10% ntawm tag nrho cov qe ntshav dawb hauv cov hlab ntsha. Monocyte muaj oval-puab los yog taum-puab nucleus thiab tsis-granulated cytoplasm. Ntxiv mus, monocyte tuaj yeem sib txawv rau hauv macrophages thiab myeloid lineage dendritic cells. Dendritic cells yog cov tshuaj tiv thaiv kab mob, thaum macrophages yog phagocytic hlwb.
Daim duab 02: Agranular Leukocyte - Monocyte
Lymphocytes yog hom loj ntawm cov hlwb pom hauv cov kab mob lymphatic. Muaj peb hom lymphocytes li T lymphocytes, B lymphocytes thiab ntuj killer hlwb. Ntuj tua cov hlwb paub thiab rhuav tshem cov hlwb hloov lossis cov hlwb uas tau kis los ntawm cov kab mob. B hlwb tsim cov tshuaj tiv thaiv uas paub txog txawv teb chaws antigens thiab neutralize lawv.
B hlwb yog ob hom: nco B hlwb thiab tswj B hlwb. Muaj ob hom T cell. Ib hom T hlwb tsim cytokines uas ua rau lub cev tiv thaiv kab mob thaum hom thib ob tsim cov granules uas yog lub luag haujlwm rau kev tuag ntawm cov kab mob. Lymphocytes, feem ntau T thiab B hlwb, tsim cov hlwb hlwb uas muab kev tiv thaiv ntev ntev tiv thaiv kab mob tshwj xeeb.
Dab tsi yog qhov zoo sib xws ntawm Granular thiab Agranular Leukocytes?
- Granualr thiab agranular leukocytes yog lub cev tiv thaiv kab mob.
- Lawv yog cov qe ntshav dawb nucleated tsim thiab muab los ntawm ntau lub hlwb hauv cov pob txha.
- Cov hlwb no tiv thaiv peb los ntawm kev tawm tsam cov kab mob sib kis lossis cov tshuaj tiv thaiv uas ua rau muaj kab mob.
- Lawv circulate ntawm lub circulatory system.
- Vim li no, lawv pom nyob rau hauv cov ntshav thiab lymphatic system.
Qhov txawv ntawm Granular thiab Agranular Leukocytes yog dab tsi?
Granular leukocytes muaj granules hauv lawv cov cytoplasms thaum agranular leukocytes tsis muaj granules hauv lawv cytoplasms. Yog li, qhov muaj thiab tsis muaj granules hauv cytoplasm yog qhov sib txawv tseem ceeb ntawm granular thiab agranular leukocytes. Ntxiv mus, muaj peb lub ntsiab ntawm granular leukocytes li neutrophils, eosinophils thiab basophils thaum muaj ob lub ntsiab ntawm agranular leukocytes li monocytes thiab lymphocytes. Yog li, peb tuaj yeem xav txog qhov no ib yam li qhov sib txawv ntawm granular thiab agranular leukocytes.
Summary – Granular vs Agranular Leukocytes
Leukocytes yog cov hlwb tseem ceeb ntawm kev tiv thaiv kab mob hauv peb lub cev. Lawv tiv thaiv peb ntawm cov kab mob invading uas tuaj yeem cuam tshuam kev ua haujlwm ib txwm muaj. Muaj ob hom leukocytes tseem ceeb: granulocytes thiab agranulocytes. Granular leukocytes muaj granules hauv lawv cytoplasm thaum agranular leukocytes tsis muaj granules. Qhov no yog qhov sib txawv tseem ceeb ntawm granular thiab agranular leukocytes. Neutrophils, eosinophils thiab basophils yog granular leukocytes thaum lymphocytes thiab monocytes yog agranular leukocytes.
