Kuj hu ua erythrocytes, RBCs yog hom feem ntau ntawm ntawm tes pom hauv ntshav , nrog txhua cubic millimeter ntawm ntshav muaj 4-6 lab hlwb . Nrog txoj kab uas hla tsuas yog 6 µm, RBCs yog me me txaus nyem los ntawm qhov tsawg tshaj plaws ntshav nkoj.
Ua li no, 4 hom qe ntshav yog dab tsi?
Nws muaj plaub ntu tseem ceeb: ntshav, cov qe ntshav liab , cov qe ntshav dawb, thiab cov platelets.
Ib sab saum toj, cov ntshav ntshav yog dab tsi? A ntshav ntshav , tseem hu ua hematopoietic ntawm tes , hemocyte, lossis hematocyte, yog a ntawm tes tsim los ntawm hematopoiesis thiab pom feem ntau hauv ntshav . Hom loj ntawm cov qe ntshav suav nrog; Liab cov qe ntshav (erythrocytes) Dawb cov qe ntshav (cov leukocytes)
Thiaj li, 3 hom qe ntshav yog dab tsi?
Muaj peb hom kab mob nyob hauv cov ntshav: cov qe ntshav liab (los yog erythrocytes ), cov qe ntshav dawb (los yog cov leukocytes ) thiab cov platelets (los yog thrombocytes ).
Cov hom ntshav ntshav 3 yam twg thiab lawv lub luag haujlwm yog dab tsi?
Ntshav tau ua los ntawm cov ntshav feem ntau, tab sis 3 hom tseem ceeb ntawm cov ntshav xa mus nrog cov ntshav:
- Platelets pab cov ntshav kom khov. Kev txhaws ua kom cov ntshav tsis ntws tawm ntawm lub cev thaum cov hlab ntsha lossis cov hlab ntsha tawg.
- Cov qe ntshav liab nqa cov pa.
- Cov qe ntshav dawb tiv thaiv kab mob.

Cov kab mob tseem ceeb ntawm kev txhawj xeeb thaum tham txog cov txheej txheem cov kab mob hauv cov ntshav yog dab tsi?
Cov kab mob tseem ceeb ntawm kev txhawj xeeb yog tib neeg kev tiv thaiv kab mob tsis zoo (HIV), kab mob siab B (HBV), thiab kab mob siab C (HCV). Cov neeg ua haujlwm thiab cov tswv ntiav haujlwm yuav tsum ua kom muaj txiaj ntsig ntawm kev tswj hwm kev tsim vaj tsev thiab kev ua haujlwm txhawm rau tiv thaiv kom tsis txhob muaj ntshav thiab lwm yam kua hauv lub cev
Dab tsi tsuas yog lim los ntawm cov hlab ntshav los ntawm glomerulus thiab tsis rov qab nqus mus rau hauv cov hlab ntshav tab sis tawm los ntawm cov zis?
Creatinine yog cov khoom pov tseg los ntawm cov leeg tawg thiab raug tshem tawm los ntawm cov ntshav los ntawm glomerulus ntawm nephron. Nws tsuas yog cov khoom uas tsuas yog lim tawm ntawm cov ntshav tab sis TSIS tau rov ua dua rau hauv lub cev. Nws raug tso tawm los ntawm cov zis
Puas yog tag nrho cov hlab ntsha nqa cov ntshav oxygenated thiab cov leeg nqa cov ntshav deoxygenated?
Cov hlab ntsha ua ib feem ntawm lub circulatory system. Cov hlab ntsha nqa cov ntshav oxygenated tawm ntawm lub plawv mus rau cov ntaub so ntswg, tshwj tsis yog cov hlab ntshav hauv lub ntsws, uas nqa ntshav mus rau lub ntsws rau cov pa oxygen (feem ntau cov leeg ntshav nqa cov ntshav deoxygenated mus rau lub plawv tab sis cov leeg hauv ntsws nqa cov ntshav oxygenated ib yam)
Cov kua ntshav ntshav yog dab tsi tom qab cov qe ntshav thiab cov ntshav khov tau raug tshem tawm?
Cov ntshav yog cov kua ntshav tom qab cov qe ntshav thiab cov protein sib xyaw tau raug tshem tawm. cov pa roj ntshav suav nrog oxygen, carbon dioxide, thiab nitrogen
Dab tsi yog lub npe ntawm cov hlab ntshav uas nqa ntshav ntshav los ntawm lub taub hau caj dab thiab caj npab mus rau sab xis atrium?
Superior vena cava
